Please help I'm so stuck. I'm supposed to graph each equation using intercepts. Solve for x. Solve for y.

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

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.

If the scale factor between two circles is 2x/5y what is the ratio of their areas?
