NEED HELP ASAP The length of a rectangle is 3 times its width. The width of the rectangle is x. The perimeter of the rectangle is equal to the expression below.

Which expression also represents the perimeter of the rectangle?
6x
8x

9x2

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
