Answer:

A

Step-by-step explanation:

the first thing you should do while completing the square should be moving your 'c' value to the other side of the equation!

do so by subtracting 8 on both sides,

your new equation should now look like x^2 -6x = -8

that is the first step of completing the square!

i hope this helps!!

you can totally bring your grade in math up!!

i believe in you!

stay safe!

The length is 2 feet longer than the width. The perimeter is 36 feet, what is the length?
SOVA2 [1]

Answer:

The length would be 10ft and the width would be 8ft

Step-by-step explanation:

For the purpose of this, we'll set the width as x. We can then define the length as x + 2 since we know it is 2 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.

P = 2l + 2w

36 = 2(x + 2) + 2(x)

36 = 2x + 4 + 2x

36 = 4x + 4

32 = 4x

8 = x

Now since we know that the width is 8ft, we can add 2ft to it to get the length, which would be 10ft.
