Step-by-step explanation:

Expanding brackets means multiplying every term inside the bracket by the term on the outside and then collecting like terms with the aim of removing the set of brackets

$x(3x + 2) = 3 {x}^{2} + 2x$

Answer:

3x² + 2x

Step-by-step explanation:

Given equation, x(3x + 2)

= x(3x + 2)

Distributive property

= {(x * 3x) + (x * 2)}

= {(1 * x * 3 * x) + (1 * x * 1 * 2)}

Rearranging like terms

= {(1 * 3 * x * x) + (1 * 1 * 2 * x)

= [{(1 * 3) * (x * x)} + {(1 * 1 * 2) * x)}]

= {(3 * x²) + (2 * x)}

= (3x²) + (2x)

= 3x² + 2x

A rectangular portrait is 2 yards wide and 2 yards high. It costs $7.61 per yard to put a gold frame around the portrait. How much will the frame cost?

Answers

Answer:

$60.88

Step-by-step explanation:

2 yards wide and 2 yards high so thats 2 yards per side x 4 is 8, 8 x $7.61 is $60.88

hope this helps:)

a 2 by 2 portrait would look like this

then, we multiply the 8 yards by the $7.61.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Given line AB, use similar triangles to prove that the slope of line AB is the same between any two points on the line.

1. Create two similar, but not equal, right triangles using segments of line AB as the hypotenuse of each triangle. For the first right triangle use point A(-5,-1) and choose another point on the line to form the hypotenuse. For the second right triangle use point B(4,3.5) and choose another point on the line to form the hypotenuse. For each point used to create the triangles, name the point with a capital letter and coordinates. For example, the triangle using point A could be named ΔACE and the triangle using point B could be named ΔBDF.
2. For the pair of similar triangles created in Part 1, list three pairs of corresponding angles that are equal and three sets of proportionate sides.
3. Use the pair of similar triangles created in Part 1 to demonstrate that the slope of line is the same between any two points on the line.

In your final answer, include a copy of your graph labeling original line AB, and all of Parts 1-3 Be sure to show the vertical and horizontal lengths used for the rise and run of the slope. To submit your answers, use a word processing program or handwritten solutions.

Common Assessment 5: Hypothesis Testing Math 146 Purpose In this assignment you will practice using a p-value for a hypothesis test. Recall that a p-value is the probability of achieving the result seen under the assumption that the null hypothesis is true. Using p-values is a common method for hypothesis testing and scientific and sociological studies often report the conclusion of their studies using p-values. It is important to understand the meaning of a p-value in order to make proper conclusions regarding the statistical test. Task Since its removal from the banned substances list in 2004 by the World Anti-Doping Agency, caffeine has been used by athletes with the expectancy that it enhances their workout and performance. However, few studies look at the role caffeine plays in sedentary females. Researchers at the University of Western Australia conducted a test in which they determined the rate of energy expenditure (kilojoules) on 10 healthy, sedentary females who were nonregular caffeine users. Each female was randomly assigned either a placebo or caffeine pill (6mg/kg) 60 minutes prior to exercise. The subject rode an exercise bike for 15 minutes at 65% of their maximum heart rate, and the energy expenditure was measured. The process was repeated on a separate day for the remaining treatment. The mean difference in energy expenditure (caffeine-placebo) was 18kJ with a standard deviation of 19kJ. If we assume that the differences follow a normal distribution can it be concluded that that caffeine appears to increase energy expenditure?

The following data was taken from its financial statements last year:Annual sales $10,200,000Cost of goods sold $6,630,000Inventory $3,200,000Accounts receivable $2,200,000Accounts payable $2,400,000Cranked Coffees CFO is interested in determining the length of time funds are tied up in working capital. Use the information in the preceding table to complete the following table. (Note: Use 365 days as the length of a year in all calculations, and round all values to two decimal places.)ValueInventory conversion period 46.93; 41.71; 176.71; or 39.11Average collection period 27.25; 78.73; 24.38; or 22.94Payables deferral period 32.50; 41.07; 33.24; or 132.13Cash conversion cycle 39.62; 122.77; 37.54; 45.88B: Both the inventory conversion period and payables deferral period use the average daily COGS in their denominators, whereas the average collection period uses average daily sales in its denominator. Why do these measures use different inputs?Inventory and accounts payable are carried at cost on the balance sheet, whereas accounts receivable are recorded at the price at which goods are sold.Current assets should be divided by sales, but current liabilities should be divided by the COGS.C. Is there generally a positive or negative relationship between net working capital and the cash conversion cycle?(In other words, if a firm has a high level of net working capital, is it likely to have a high or low cash conversion cycle?)There is a positive relationship between net working capital and the cash conversion cycle.There is a negative relationship between net working capital and the cash conversion cycle.D. What are the four key factors in a firms credit policy?Credit terms, discounts, credit standards, and collection policyCredit period, discounts, credit standards, and collection policyE. If the credit terms as published by a firm were 2/15, net 60, this means the firm will:allow a 2% discount if payment is received within 15 days of the purchase, and if the discount is not taken the full amount is due in 60 days.allow a 15% discount if payment is received within 2 days of the purchase, and if the discount is not taken the full amount is due in 60 days.F. The management at Cranked Coffee Company wants to continue its internal discussions related to its cash management. One of the finance team members presents the following case to his cohorts:Case in DiscussionCranked Coffee Companys management plans to finance its operations with bank loans that will be repaid as soon as cash is available. The companys management expects that it will take 40 days to manufacture and sell its products and 35 days to receive payment from its customers. Cranked Coffees CFO has told the rest of the management team that they should expect the length of the bank loans to be approximately 75 days.Which of the following responses to the CFOs statement is most accurate?The CFO is not taking into account the amount of time the company has to pay its suppliers. Generally, there is a certain length of time between the purchase of materials and labor and the payment of cash for them. The CFO can reduce the estimated length of the bank loan by this amount of time.The CFOs approximation of the length of the bank loans should be accurate, because it will take 75 days for the company to manufacture, sell, and collect cash for its goods. All these things must occur for the company to be able to repay its loans from the bank.Setting and implementing a credit policy is important for three main reasons:It has a minor effect on sales, it influences the amount of funds tied up in receivables, and it affects bad debt losses.It has a major effect on sales, it influences the amount of funds tied up in receivables, and it affects bad debt losses.
