The height of the tank must be at least 1 foot, or 12 inches. We know the floor area (which is length x width) must be at least 400 inches. Therefore these minimum dimensions already tell us that the minimum volume is 400 x 12 = 4800 cubic inches. Since we have a maximum of 5000 cubic inches, the volume must be within the range of 4800 - 5000 cubic inches.
We can set the height at exactly 1 ft (or 12 inches). Then we can select length and width that multiply to 400 square inches, for example, L = 40 inches and W = 10 in. This gives us a tank of dimensions 40 x 10 x 12 = 4800 cubic inches, which fits all the criteria.

Answer:
A, C
Step-by-step explanation:
First distribute
a(b+c)=ab+ac
-2(x+4)=-2x-8
now we have
-2x-8-8=4
-2x-16=4
add 16 both sides
-2x=20
divide bot sides by -2
x=-10
