Answer:
14
Step-by-step explanation:
(7x-1)+(6x-1)=180
13x-2=180
13x=182
x=14
Width = x
Length = 2x+1
1/2 the permiter = l + w
1/2 perimeter = 176 /2 = 88
so we have x + 2x+1 = 88
combine like terms:
3x +1 = 88
subtract 1 from both sides:
3x = 87
divide both sides by 3
x = 87 / 3 = 29
with = 29 feet
length = 29 x 2 = 58 +1 = 59 feet
check: 59 +59 +29+29 = 176
"Common" means "same for both". If two numbers have a factor that's the same, then it's a common factor of them. Example: 2 is a common factor of 6 and 10. It's NOT the only factor of either number, but it's a factor that they share ... a 'common' one.
