it's C because the floor area is 120 square feet and the walls are 8 feet so if you multiply 120 × 8 you get 960.
Answer:
94 ft
Step-by-step explanation:
A rectangle shares 2 congruent lengths & 2 congruent width sides.
The perimeter is the total measurement of all sides added together. Solve:
2(15) + 2(32) = 30 + 64 = 94
94 ft is your answer.

Eloise made these steps well:
Square root of negative 2x plus 1 - 3 = x
Square root of negative 2x plus 1 - 3 + 3 = x + 3
The error comes in the next step:
Square root of negative 2x plus 1 = x + 3
Square root of negative 2x plus 1 -1 = x + 3 - 1
Square root of negative 2x = x + 2
the number one is inside the root, therefore they can not be subtracted.
answer
error in the step:
Square root of negative 2x = x + 2
Answer:
76˚
Step-by-step explanation:
All angles of a triangle total up to 180˚ so we can make this equation:
x - 14 + 1/2x + 7 + 2x - 128 = 180
3.5x - 135 = 180
3.5x = 315
x = 90
Angle A is x - 14
90 - 14
76
The volume of a sphere is:
V=(4πr^3)/3, and you are told that r=5in so
V=(4π125)/3
V=500π/3 in^3
V≈523.60 in^3
