The front of an a-frame house is in the shape of a triangle. the height of the house is 20 feet. the area of the front of the a-frame house is 600 square feet. write and solve an equation to find the base of the a-frame house.

1. are the triangles similar and if so why? what is the value of x? show your work.

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

Atriangle has an area of 72 square inches. if the base of the triangle has a length of 18 inches, what is the height of the triangle? use the formula for the area of a triangle: area = (base)(height) type a numerical answer in the space provided. do not include the units or spaces in your answer.
