Expand (2x-3y+3)^2 PLEASE HELP!!

Anon25 [30]

Answer:

4x² + 9y² + 12x - 18y - 12xy + 9

Step-by-step explanation:

Given

(2x - 3y + 3)² = (2x - 3y + 3)(2x - 3y + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(2x - 3y + 3) - 3y(2x - 3y + 3) + 3(2x - 3y + 3)

Distribute the 3 parenthesis

= 4x² - 6xy + 6x - 6xy + 9y² - 9y + 6x - 9y + 9 ← collect like terms

= 4x² + 9y² + 12x - 18y - 12xy + 9

Veronika [31]

13 3/4 + x = 7 1/4

becomes x = 13 3/4 / 7 1/4

13 3/4 = 55/4

7 1/4 = 29/4

55/4 / 29/4 = 55/4 * 4/29 = 220/116

220/116 reduces to 1 26/29

Bob says that he can find the area of the triangle below using the formula: A = <img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D

Goryan [66]

Answer:

No.

Step-by-step explanation:

No, Bob is not correct.

The formula he's using is the following:

$A=\frac{1}{2} ab\sin(C)$

The important thing here is that the angle is between the two sides.

In the given triangle, 120 is not between 8 and 18. Therefore, using this formula will not be valid.

Either Bob needs to find the other side first or find the angle between 8 and 18.
