The first thing you want to do is combine like terms. This means you should have all the x's on one side and the constants (numbers) on the other side. You can subtract 5x from both sides of the equation and then add 7 to both sides. This gives you -2x=26. Divide both sides be -2 to isolate the variable and your answer is x=-13. Hope this helped!

Step-by-step explanation:
Answer:32cm
Step-by-step explanation:
Length=L
Area=64
Area=L x L
64=L^2
L^2=64
Take them square root of both sides
√(L^2)=√(64)
L=8
Perimeter of square=4 x L
Perimeter of square=4 x 8
Perimeter of square=32
Perimeter =32cm
