The perimeter of a square box is 12x + 32. Drag numbers to complete an equivalent expression that shows the perimeter as four times the side length of the box. Numbers may be used once, more than once, or not at all.

4L = 4(3x + 8)

So,we can conclude that four times the side length is equal to the perimeter.

Step-by-step explanation:

Let the side length of the square be L.

We know that perimeter of a square is given as: P = sum of all 4 sides.

Thus, since all sides of a square are equal, then P = L + L + L + L = 4L

We are given that the perimeter is 12x + 32.

Since we have established the formula for perimeter as 4L

Thus;

4L = 12x + 32

So, if we factorize the right hand side, we have;

4L = 4(3x + 8)

Comparing both sides, we can see that L = 3x + 8

Thus,we can conclude that four times the side length is equal to the perimeter.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
