The width of a rectangle measures (3c-9d)(3c−9d) centimeters, and its length measures (8c-2d)(8c−2d) centimeters. Which expressi
Vsevolod [243]

The expression for the perimeter of the rectangle is 2(11c - 11d)

Perimeter of a rectangle = 2(length + width)

Length = 3c - 9d

Length = 3c - 9d Width = 8c - 2d

The expression for the perimeter can be expressed thus :

2(3c - 9d + 8c - 2d)

Collect like terms :

2(3c + 8c - 9d - 2d)

2(11c - 11d)

Hence, the expression for the perimeter of the rectangle is 2(11c - 11d)

Please explain to me how to find the solution of 3n+8=20 Thank you
allsm [11]
First, you subtract 8 by both sides ( 8-8/ 20-8) so now your equation is 3n=12. Next, you multiply 3n by 3, and get 0, and 12 multiplied by 3 and the answer is 36! Hope this helped.
