Can someone help me please

51ft, 17ft, 39ft

Step-by-step explanation:

longest = x

2nd = x

3rd = x - 12

P = 107

a + b + c = Perimeter

x + x + x - 12 = 107

x -12 = 107

x = 119

x = 51

x = 17

x - 12 = 39

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
