A tree was 9 feet tall. One year later, the tree was 16 feet tall. Write an equation and use mental math to find how many feet f the tree grew.

Step-by-step explanation:

let the height height of the tree be "h"

Hence the tree's height h=9 ft

one year later,let the height of the tree increased by x ft

hence

--------This is the equation for the growth of the tree

In order to solve for the added height(growth) of the tree we need to solve for x

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
