12.16
13.182.8
14.220
15.499
16.19.5
Well for one, the floor and the ceiling do not need wallpaper. So you would only find the surface area each side. (48, 48, 80, 80) Then you would add all four together. (256ft squared)
The answer is 'C.'
Midpoint formula (x1 + x2) / 2, (y1 + y2)/2
(-2,2)...x1 = -2 and y1 = 2
(3,-1)...x2 = 3 and y2 = -1
now we sub
m = (-2 + 3) / 2 , (2 - 1) / 2
m = (1/2, 1/2) <===
Answer:
plug it into the pythagorean theorem formula
Step-by-step explanation:
since the pythagorean theorem is a^2+b^2=c^2, you have to plug in the lengths of the leg and the hypotenuse to the formula. If you were trying to find a, you would plug in the second leg into b and the hypotenuse into c. so if for example you needed to find a and the second leg was 2 inches while the hypotenuse was 5 inches, the formula would be a^2+2^2=5^2. then solve it like a regular equation, so a^2+4+25, a^2=21, and you would do the square root of that answer. hope that helped.
