It should be B

Calculate the slopes using the change of y over the change in x

-2/2=-1

That’s the only option with a slope of -1

Answer:

The answer is 4a

Step-by-step explanation:

1) Simplify 4a² + 12a² to 16a².

$\sqrt{ {16a}^{2} }$

2) Use this rule:

$\sqrt{ab} = \sqrt{a} \sqrt{b}$

$\sqrt{16} \sqrt{ {a}^{2} }$

3) Since 4 × 4 is 16, the square root of 16 is 4.

$4 \sqrt{ {a}^{2} }$

4) Simplify.

$4a$

Therefor, the answer is 4a.
