Answer:
are u serious this is the most easiest question ive ever answered but the answer is 9 because u can minus 12-3 and get 9 so x=9
Step-by-step explanation:
X^2+11x+18<0 ----- Subtract 18 from both sides
(x+2)(x+9)=0-------- Factor the left side
------Set factors equal to zero
Your answer is -9<x<-2
Answer:
The answer is 4.
Step-by-step explanation:
Since the fractions have the same denominators, all you have to do is subtract 1/5 from 1/5. When you subtract the numerators (1-1) you get 0. That would make the fraction 0/5, but that does not have to be included in the answer since it has no value. Subtract the whole numbers (23-19) to get 4.

The surface area of the box is being referred to as A
The surface area will be the sum of the four rectangular sides' areas and the base area.
Base area = x²
Rectangular side area = xh
A = x² + 4xh
Volume is, as you said,
V = x²h
Lets substitute h from the formula of A to obtain A in our final answer. Substituting x is possible, but more difficult
(A - x²)/4x = h
V = (x²) * (A - x²)/4x
V = (Ax - x³)/4
