A circular window is surrounded by a circular frame. The radius of the window is m − 2 and the radius of the full circle formed by the frame is m + 2. Write a polynomial that represents the area of just the frame itself, not including the space covered by the window.
(The area of a circle is given by A = πr 2, where r represents the radius of the circle.)

answer: 45

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
