All you have to do is substitute 2 and 7 in for x in the function.

f(2) = 2(2) + 7

= 11

f(7) = 2(7) + 7

= 21

Answer:

about 89.27 inches

Step-by-step explanation:

This is a right triangle question

c^2 = a^2 + b^2

c^2 = 15^2 + 88^2

c^2 = 225 + 7744

c^2 = 7969

Take the square root of both sides

c = 89.2692556259

c ≈ 89.27 inches
