Answer:
The answer is B. 3x+12
Step-by-step explanation:
you have to use the distributive property for this
3 times x and 3 times 4 equals 3x+12
C is the answer. The height of a cylinder is the perpendicular distance between the bases.
The bottom trapezoid is
(1/2) * h * (b2 + b1) =
(1/2)*11 * (31+25)
(1/2) * 11 * 56
308
The top parallelogram is
b * h = 12 * 14 = 168
308 +168 = 476 ft^2
Letter B
