Answer: No solutions
Step-by-step explanation:
Multiply both sides by -7 and switch the sign. t<-70
2/3x+3=6
2/3x=3
x= 3*3/2
x=9/2=4.5

Answer:
Perimeter of polygon B = 80 units
Step-by-step explanation:
Since both polygons are similar, their corresponding sides and perimeters are proportional. Knowing this we can setup a proportion to find the perimeter of polygon B.

Let
be the perimeter of polygon B. We know from our problem that the side of polygon A is 24, the side of polygon B is 15, and the perimeter of polygon A is 128.
Let's replace those value sin our proportion and solve for
:





We can conclude that the perimeter of polygon B is 80 units.
