Solution:

The equation Annie solved was;

7x+16=2(x+2)

Then, we have;

7x+16=2x+4

Collect like terms;

\begin{gathered} 7x-2x=4-16 \\ 5x=-12 \end{gathered}

Divide both sides by 5;

\begin{gathered} \frac{5x}{5}=-\frac{12}{5} \\  \\ x=-2.4 \end{gathered}

Thus, Annie is not correct.

CORRECT OPTION: (B) No, Annie is not correct

Use the perfect square method <br> (3x + 3)^2 = 36
kkurt [141]

Factor out the common term; 3

(3(x + 1))^2 = 36

Use the Multiplication Distributive Property; (xy)^a = x^ay^a

3^2(x + 1)^2 = 36

Simplify 3^2 to 9

9(x + 1)^2 = 36

Divide both sides by 9

(x + 1)^2 = 36/9

Simplify 36/9 to 4

(x + 1)^2 = 4

Take the square root of both sides

x + 1 = √4

Since 2 * 2 = 4, the square root of 2 is 2

x + 1 = 2

Break down the problem into these 2 equations

x + 1 = 2

x + 1 = -2

Solve the first equation; x + 1 = 2

x = 1

Solve the second equation; x + 1 = -2

x = -3

Collect all solutions;

<u>x = 1, -3</u>
