X + y = 8
x - y = 12
--------------add
2x = 20
x = 20/2
x = 10
x + y = 8
10 + y = 8
y = 8 - 10
y = -2
ur numbers are 10 and -2
The formula of that is 24
Perimeter = 30 inches
Length = 3x
Width = X
P = 2L + 2W
30 = 2(3x) + 2(X)
30 = 6x + 2x
30 = 8x
30/8 = 8x/8
3 6/8 = 3 3/4 = X
X = 3.75 inches
The width is 3.75 inches and red length would be 3 times as much or 3(3.75) = 11.25 inches.
