A 28-inch
board is to be cut into three pieces so that the second piece is
twicetwice
as long as the first piece and the third piece is
44
times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces
1st piece x=28
2nd piecex=28 squared which is 784
3rd piece 28 to the fourth power which is 3.77

what's all this power stuff?
1st piece = x
2nd piece = 2x
3rd piece = 4x
So, you have
x+2x+4x = 28
x = 4
1st piece = x
2nd piece = 2x
3rd piece = 4x
So, you have
x+2x+4x = 28
x = 4
A 20 inch board is 4 times to be cut into three pieces so that the second piece is as long as the first piece and the third piece is 5 times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces.
