Plz help me, what Did I do wrong. Two polygons are similar. The perimeter of the larger polygon is 120 yards and the ratio of the corresponding side lengths is $\frac{1}{6}$
. Find the perimeter of the other polygon.

20 yards

Step-by-step explanation:

You have to take of 120, giving you 20.

Simplify :
12+-5x+6x=4
combine like terms :
-5x+6x=1x
12+1x=4
solving :
12+1x=4
solving for variable ‘x’
move all terms containing x to the left, all other terms to the right, add ‘-12’ to each side of the equation
12+-12+1x=4+-12
combine like terms:
then divide each side
your answer : x=-8
