Answer:

True

Step-by-step explanation:

Let's take a problem such as 3x-2=6

To isolate the variable, you must get rid of everything on one side and essentially do the inverse to the other side. We see -2, so you have to add 2 to each side.

Now you have 3x=8

Next, we device each side by 3. Right now, x is being multiplied by 3 so we have to do the inverse.

Answer is x = 8/3 or 2.666666666666667

Westkost [7]

Answer:

18 ft and 30 ft

Step-by-step explanation:

The new dimensions will be:

10 + x and 22 + x

The area is 540

Using area equation we get:

(10 + x)(22 + x) = 540
x² + 32x + 220 = 540
x² + 32x = 320
x² + 2x*16 + 256 = 320 + 256
(x + 16)² = 576
x + 16 = √576 (Ignoring the negative root as the length is never negative)
x + 16 = 24
x = 8

The new dimensions are:

10 + 8 = 18 ft and
22 + 8 = 30 ft
