Answer:

see below

Step-by-step explanation:

24 - 3 x = -27

Subtract 24 from each side

24-24 - 3 x = -27-24

-3x =-51

Divide each side by -3

-3x/-3 = -51/-3

x = 17

Check

24 -3(17) = -27

24 -51 = -27

-27 = -27

Select the correct answer.
Ierofanga [76]

Answer:

19.2x+96 units

Step-by-step explanation:

The perimeter of a square is 4 times the length of one side.

The length of the sides of a square is given by the expression 4.8x+24

To find the perimeter, we multiply this expression by 4.

Perimeter=4(4.8x+24)

We expand to obtain:

Perimeter=4*4.8x+4*24

This simplifies to:

Perimeter=19.2x+96
