45 is exactly half of 90
that means 45 is 50% of 90.
I am not in 8th grade but it might be the 2nd one
<span>x+2 = -x+6
</span>2x+2 = 6
2x = 4
x = 2
Add 121/4 to each side:
x²+11x+121/4 < 121/4-8
x²+11x+121/4 < 89/4
(x+11/2)² < √89/2 ⇒ -√89/2 < x+11/2 < √89/2
-11/2-√89/2 < x < -11/2+√89/2
The answer is 3.85555556 because the ratio is 9:1 the length 34.7 so that means the length will be 9 times the width so you divide.
