Answer:Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.

Let x = width and x+10 = length

So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.

Thus the area is 5⋅15=75m2

Answer:

The answer is x = -32

Step-by-step explanation:

In order to find the value of x, e must first distribute the 6 into the parenthesis.

6(x - 7) = 8x + 22

6x - 42 = 8x + 22

Now we will add/subtract values so that all x values are on the right and all number values are on the left.

6x - 42 = 8x + 22

-42 = 2x + 22

-64 = 2x

Now to get the final answer, divide both sides by 2.

-32 = x
