HELP

Answer 1

A. 22

Explanation:

4^2 + (4)(1.5)

4 multiplied by 1.5 is 6.

4 to the power of 2 is 16.

16 + 6 = 22.

Therefor, your answer would be A. 22

Hope this helps!

Answer 2

So if you have r^2 + 4s and r=4 and s = 1.5 r^2 is 4^2 which is 16 and 4s is 1.5 x 4 which is 6 so you do 16 + 6 which is 22 so the correct answer is a.
