Here's an example

Simplify by collecting like terms: 4(x2y + 7y) – 5y(3x2 – y) – 10y

A) −11x2y + 5y2 + 18y

B) 4x2y + 11y – 8yx2 – 16y

C) 4x2y + 18y – 15yx2 + 5y2

D) 4x2y – 5y(3x2 – y) – 3y

A) −11x2y + 5y2 + 18y

Correct. 4(x2y + 7y) – 5y(3x2 – y) – 10y = 4x2y + 28y – 15yx2 + 5y2 – 10y = 4x2y + 18y – 15yx2 + 5y2 = −11x2y + 5y2 + 18y.

B) 4x2y + 11y – 8yx2 – 16y

Incorrect. The 4 is distributed to both terms in the parentheses by multiplying each term by 4 resulting in 28y, not 11y. The −5y is similarly distributed to each term in the parentheses, resulting in −15yx2 + 5y2. The correct answer is −11x2y + 5y2 + 18y.

C) 4x2y + 18y – 15yx2 + 5y2

Incorrect. This polynomial can be further simplified by combining the like terms 4x2y and −15yx2. The order of the variables in a term does not matter. The correct answer is

−11x2y + 5y2 + 18y.

D) 4x2y – 5y(3x2 – y) – 3y

Incorrect. Before combining like terms, you must distribute to clear the parentheses. The correct answer is −11x2y + 5y2 + 18y.

What is the length of side x? (possibly use similar triangles)

weeeeeb [17]

Law of Sines

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

$\frac{sin(90)}{14.6} = \frac{sin(45)}{x}$

Cross multiply

x*sin(90) = 14.6sin(45)

x = 14.6sin(45)

x = 10.3

A video game developer wants to know how long it takes people to finish playing their new game. They surveyed a random sample of

Nadya [2.5K]

Based on the data, the median time it takes players to complete the game is 1148 minutes.

<h3>What is the median?</h3>

It is the mathematical value that is the middle when values are sorted.

<h3>How to find the median time?</h3>

Organize the values

457 - 548- 866 - 952 - 976 - 1037 - 1148 - 1235 - 1245- 1431-1486 - 1759 - 1864

Identify the value of the middle

Considering there are 13 values, the value of the middle is the value number 7 or 1148.

Note: This question is incomplete because the data is missing, below I attached the missing section,
