Find the missing factor. y2 + 8y - 9 = (y + 9)

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

only 2 solutions are positive

also the part with what number should be added to both sides of the equation

should be 2 or 4
