Can someone help me???

45 inches.

Step-by-step explanation:

As the perimeters are the same, you know that 5(0.5x-1) = 3(x-5).

This can be expanded as 2.5x - 5 = 3x - 15.

Now rearrange to find x: -5 = 0.5x -15

                                       10 = 0.5x

                                       20 = x

And substitute x back into one of the formulas: 3(20-5) = 60-15 = 45 inches.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
