99/36= 11/4= 2.3 is my answer
First let's review how to expand this!
(ax+b)^2=a^2*x^2+2abx+a^2
In this case
(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2
=4x^2+2x+1/4
Done!

Is there a picture that goes along with this?
Answer:
m∠2 = 90°
Step-by-step explanation:
Here's a postulate:
If a line is perpendicular to another line, then they make up 90° on both sides.
OR
If a⊥b, then ∠ are 90°
