A triangle has side lengths of 3m2 + In-2, -2m2 + 7m - 4n+ 5 and 8m2+n+ + 6m + 1. What is the perimeter of the triangle?
2:
a)
11m2 + m - 11n +6
b) 9m2 + m2 + 13m + 3n + 8
3:
c) None of these
d)
24m2 - 2n +42m - 28n-10
e) 11m2 - n° +13m + 3n+4

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

if x = 1, then the answer is 3.5

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
