The appropriate choice is ...
(25−2x)(20−2x)x
_____
When x is cut from each side of the 25 dimension, the remaining dimension of the bottom of the box is 25-2x. Similarly, when x is cut from each side of the 20 dimension, the remaining dimension of the bottom of the box is 20-2x. The length of the side that is folded up is x, so that is how deep the box is.
The volume is the product of the dimensions of the bottom and the side:
(25−2x)(20−2x)x
Answer:
1. 6n
2. 6×30=180
Step-by-step explanation:
180 is the 30th term
What's a pair of numbers that are addends of -6 but factors of 5? That would would be -5 & -1. Now we can break it up into groups. That will give us (x^2 - 5x)(x - 1). Now do the same for the second one. That will give us (x^2 - 8x)(x - 1x).
