Answer:
40-15-12= 13
Step-by-step explanation:
15 + 12 + x = 40
Solve for x
Perimeter = Side + Side + Side
Side 1 = x
Side 2 = x + 7
Side 3 = 2x-7
Plug into the equation:
84 = x + (x + 7) + (2x-7)
84 = x + x + 7 + 2x - 7
Combine like terms:
84 = 4x
Divide by 4 and solve for x:
21 = x
Side 1 = 21
Side 2 = 28
21+7=28
Side 3 = 35
21(2) - 7 = 42 - 7 = 35
