The expression x3 + 16x2 + 68x + 80 represents the volume of a flower box in cubic inches. The expression x + 4 represents the depth of the box. Assume
that the length is greater than the height and that linear expressions with
integer coefficients represent both.
a. What are the other dimensions of the flower box?
b. If x= 3, what are the dimensions of the flower box?

coins of silver or gold

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
