Answer:
Equation: 3(x+5)=60
Solution: 15 inches
Step-by-step explanation:
Let x represent the original side length of the equilateral triangle. Then, the new length of each side is x+5. Because a triangle has three sides, the new perimeter is 3(x+5), which is 60 inches. Dividing both sides by 3, we get that x+5=20, so x=15.

Answer:
Below.
Step-by-step explanation:
So 4-6 to 8-12.
4 can be devised by 12, and so can 6.
4:8 6:12
If we flip them over we can find the dilation.
so?
8:4 12:6
Each can be divided by 2.
So the factor if dilation is 2.
