NOT a function because if we have two repeating x-values and two different y-values for the same x is not a function.

a triangle has a perimeter of 49 inches. the medium side is 7 more than the short side, and the longest side is 5 times the leng

slavikrds [6]

Short side length = x
Medium side = x + 7
Long side = 5x
Total 49, so
x + x + 7 + 5x = 49
If you combine like terms:
7x + 7 = 49
Subtract 7 from both sides
7x = 42
Divide both sides by 7
x = 6 inches
