That is the inverse of the function f(x) = 2x – 10? h(x) = 2x-5
h(x) = 2x + 5
h(x) =
*x-5
{x+5
h(x) =

x = 3 ± √(5+y)

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

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
