Question

Write a function rule for the area, A, of a triangle whose base, b, is 2 cm less than seven times the height, h. What is the area of the triangle when the height is 14 cm?

Answer 1

\[A=\frac{1}{2}(7h-2)(7h)\]
A=4704

Answer 2

I think the b=(7h-2)because "b, is 2 cm less than seven times the height, h"

Answer 3

ah.. i don't know why i did that..
