We need to see the graph in order to help
Answer:
18
Step-by-step explanation:
Since you know the perimeters are equal, write your equation.
x+6 + x+6 + x+6 = x + x+6 + 2x-6
combine like terms
3x + 18 = 4x
isolate your x by subtracting 3x from each side
18 = x
check your answer:
3x + 18 = 72
4x = 72
Answer:
Third answer
Step-by-step explanation:
1 x 7 = 7
36 x 7 = 252
4a+3b-(-2a-3b)
=4a+3b+2a+3b
=6a+6b
=6(a+b)
11 i think is what the answer is.
