The length of the sides of a square is given by the expression 4.8x + 2.4. Which expression represents the perimeter of the square? A. 4.8x + 2.4 + 4 B. 19.2x + 2.4 C. 8(2.4x + 1.2) D. 4.8x + 9.6

Option C. 8( 2.4x + 1.2 )

Step-by-step explanation:

Length of the sides of a square is given by the expression ( 4.8x + 2.4 )

Then we have to find the expression that represents the perimeter of the given square.

Since perimeter of a square = 4 × ( side of the square )

                                             = 4( 4.8x + 2.4 )

                                              = 8( 2.4x + 1.2 )

Therefore, option C. 8(2.4x + 1.2) represents the perimeter of the square.

the answer is a

step-by-step explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
