Answer: 116.12
Explanation:
13 x 7 = 91
13 - 5 = 8

3.14(4)^2 = 50.24
50.24 / 2 = 25.12
91 + 25.12 = 116.12

Answer:
Step-by-step explanation:
6/x^2 + 2 x = 7
2 x^3 - 7 x^2 = -6 (for x!=0)
(2 (x^3 - 3 x^2 + 3))/x^2 = 1
300^2 + 500^2 = c^2
9000 + 250000=c^2
340000=c^2
sqrt (340000) = c
c = 583
300 + 500 + 583 = 1383
1380 is the perimeter
