Answer:
Step-by-step explanation:
The side lengths are 1/4 of the perimeter, so we can say ...
the sum of side lengths is 68 ft/4 = 17 ft
the difference of side lengths is 12 ft/4 = 3 ft
Using x to represent the side length of the smaller square, we have ...
x + (x +3) = 17 . . . . . . the larger square has side length x+3
2x = 14 . . . . . . . . . subtract 3
x = 7 . . . . . . . . divide by 2
The side lengths of the squares are 7 feet and 10 feet.

Answer:
x=3
Step-by-step explanation:
There's many ways you can begin this, I prefer getting rid of the fraction first.
Multiply both sides by 3/2 (yes, I switched it on purpose)
You get. . .
5x-6 = 9
To isolate the 5x, add 6 to both sides
5x = 15
Divide both sides by 5 and you get . . .
x=3
Answer:
25.63694268 = r
Step-by-step explanation:
The circumference is
C = 2*pi*r
161 = 2*(3.14) *r
161 = 6.28 r
Divide each side by 6.28
161/6.28 = r
25.63694268 = r
