2x + y = -2
x + y = 5
the x-coordinate of the solution to the system shown is

part a: 1.08

part b: 27.59

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
