The expression representing the height of the box is x+1.
<h3>What is volume of cuboid?</h3>
The volume of the box is the product of length, breadth and width.
The volume of the box = l x b x h
x³ + 5x² -8x - 12 = (x + 6) . (x -2) .h
= (x²+ 4x -12) .h
h = (x³ + 5x² -8x - 12) / (x²+ 4x -12)
On dividing we get
h = x +1
Therefore, the expression representing the height of the box is x +1.

The top question is B. 30, because you have to set 7y-30 equal to 4y+60 since both lengths are the same.
I think the answer is 5 because 25 divided by 5=5
n + q = 35
n = 35-q
0.05n + 0.25q = 8.15
0.05(35-q) +0.25q = 8.15
1.75 -0.05q + 0.25q =8.15
1.75 + 0.20q = 8.15
0.20q = 6.40
q = 6.40 / 0.20 = 32
