Question:

A television screen measures diagonally 50 inches and has a 14 inch width. What is the area and perimeter of the screen.

Daron C.

You would first need to find the length of the screen. You could use the pythagorean theorem to find this. 14^2 + L^2 = 50^2 this would be 196 + L^2 = 2500 subtracting 196 from both sides of the equation L^2 =2304 then square rooting both sides gives a length of L = 48. So the area of the screen is found A = L * W = 14 * 48 = 672 square inches. The perimeter is found by adding the 4 sides together. Perimeter = 14 + 48 + 14 + 48 = 124 inches

Question:

Solve the equation. 5x+3=7x-9

Daron C.

First move the variable term to one side by subtracting the 5x from both sides of the equation. This will give you 3 = 2x-9. Next add 9 to bothe sides of the equation to get the veriable term 2x alone. this will give you 12 = 2x. Last divide both sides of the equation by 2 to solve. This gives you 6 = x
