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

Answer:

ED = 32.5

BE = 14.4

Step-by-step explanation:

Ab = 20

AC = AB + 5 = 20 + 5 = 25

AC / AB = 1.25

AB * 1.25 = AC

This means that:

AE * 1.25 = ED

CD / 1.25 = BE

AE * 1.25 = ED

26 * 1.25 = 32.5

CD / 1.25 = BE

18 / 1.25 = 14.4
