The expression (x2 − 5x − 2) − (−6x2 − 7x − 3) is equivalent to 7x2 − 12x − 5 7x2 − 2x + 1 −3x2 + 6xy + 4 3x2 − 6xy − 4

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

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
