The answer is 8.72.
sqrt(76) = 2sqrt(19)
2sqrt(19) = 8.717797887
Rounded to nearest hundredth ≈ 8.72
So I have 2 answers here they are.

221.5÷20=11.075
I hope this helps!
Y=-1/20(x+3)^2
Your could always tell by which way the curve is pointing and if pointing down it’s a negative it’s pointing up it’s a positive
Hope that helped
Answer:

Step-by-step explanation:
Two angles are supplementary when they add up to 180°.
So we know that:

Supplanting we get:

We add up the X's.


Then we send 64 to the other side adding:



And then the 8 goes dividing:


First seperate the irregular shape into 2 regular shapes, by splitting the yellow part down the middle horizontally we get 2 obtuse triangles. Then we just need to find the area of both, to do this we just need base and height, this is 24 in base 15 in height
the area of each half is 180 square inches
180 + 180 = 360
the answer is A 360 square inches
