what is the pirimeter of a rectangle with a length of (3x-5) and width of (3x+5)

Sagot :

Answer:

9x²-25

Step-by-step explanation:

To get the perimeter of a rectangle you need to multiply the length and the width.

  • Which in this case is

L = (3x-5) and W = (3x+5)

P = L x W

P = (3x-5) (3x+5)

= (3)(3) (x)(x) (-5)(5)

= 9 x² -25

then combine all terms. which will be

P = 9x²-25

hope this helps.
