Question

The perimeter of a square is 68 meters. The side length can be represented as (8x - 3) meters. What is the value of x? (1 points)

2.5

8.875

8.125

1.75

Answer 1

\(P = 4a\)

Where 'a' is the side.

Plug in what we know:

\(68 = 4(8x - 3)\)

Distribute 4 into the parenthesis:

\(68 = 32x - 12\)

Add 12 to both sides, what's 68 + 12?

Answer 2

Do this one the same as the last problem. Use the side length for both L and W. You can also use the equation P = 4S instead

Answer 3

80

Answer 4

68 = 4 (8x = 3)
68 = 32x - 12
68 + 12 = 32x
80 = 32x

Answer 5

Yes, that gives us:

80 = 32x

Now we divide 32 to both sides, what's 80 / 32?

Answer 6

x = 80/32

Answer 7

2.5

Answer 8

x = 2.5

Answer 9

CORRECT!

Answer 10

Yep, you got it.
