A rancher has a square cow pen with side length x. He deicdes to change the shape of the pen while still using
the same amount of fencing materials. The equation
(x + 10)(x - 10) = 300 represents the relationship
of the new side lengths (in feet) of the pen and its area
(in square feet).
a. If 300 represents the area of the new cow pen, what
do the expressions (r + 10) and (x - 10) each
represent?

the answer is 31.27mph

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
