From the image, we have:

PS = 8 units

This means that:

P'S' = 1/2 * PS

A 40-inch board is to be cut into three pieces so that the second piece is 3 times as long as the first piece and the third piec
tiny-mole [99]

Answer:

The first piece is 5 inches long, while the second is 15 inches and the third one is 20 inches.

Step-by-step explanation:

To determine the length of the 3 pieces, knowing that the total of the board is 40 inches, and that the second measures 3 times more than the first and the third measures 4 times more than the first, the following equation must be performed:

X + 3X + 4X = 40

8X = 40

X = 40/8

X = 5

Therefore, the first piece is 5 inches long, while the second is 15 inches and the third 20 inches.
