Hello! I believe the answer is 27.71.
I hope this helps!
Answer:
Step-by-step explanation:
<u>Given</u>
- Q = 7m + 3n,
- R = 11 - 2m,
- S = n + 5,
- T = -m - 3n + 8
<u>Simplify [Q - R] + [S - T]</u>
- (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
- 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
- m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
- 10m + 7n - 14
+the larger one is double the size since 6.2 x 2 - 12.4
so 1.8 x 2 = 3.6
perimeter = 2 x 3.6 + 2 x 12.4 = 32 feet
The first step for solving this equation would be adding -2 to both sides of the equation.
