Answer:
uh i really wanna help but maybe dividing would help :)
Step-by-step explanation:
O is the midpoint so both sides FO and OG need to equal each other.
3x + 17 = 7x - 15
Subtract 3x from both sides:
17 = 4x -15
Add 15 to both sides:
32 = 4x
Divide both sides by 4:
x = 32/4
X = 8
Now you have the value of X, solve for the lengths:
FO = 3x +17 = 3(8) +17 = 24 +17 = 41
OG = 7x -15 = 7(8) -15 = 56-15 = 41
Total length would be 41 + 41 = 82
Answer:15
Step-by-step explanation:
If the two sides equal 30 then you just divide that by 2 and get your answer 15

The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:
Since the length is twice the width, we have 
, and the formula for the perimeter becomes
So, we have
