Answer:
P = 20/7 or 2 6/7
Step-by-step explanation:
We want to find the perimeter of a square
P = 4s where s is the side length
s = 5/7
P = 4* 5/7
P = 20/7
We can leave it as an improper fraction or change it to decimal form
7 goes into 20 two times 2*7 = 14 20-14 =6
The mixed number is 2 6/7
Answer:

Step-by-step explanation:
Length times width you learned about that in elementary school every one has.
Answer:
See below in bold.
Step-by-step explanation:
(A) 20 -4x=12 -x+8-3x
-4x + x + 3x = 12 + 8 - 20
0 = 0 This is an Identity.
Infinite solutions.
B). 5x+4x-3=24+8x
9x - 8x = 24 + 3
x = 27. One solution.
C. 5x+6=2x+6+3x-15
5x - 2x - 3x = -15 + 6 - 6
0 = -15
No solution.
