How would you write the expression that represents the perimeter of a rectangle measuring 9 x + 9 and 4 x - 3
Would it be 26 x + 2
Any help would be appreciated.
Thank You

To find the perimeter of a rectangle, you need to add up the lengths of all the sides. In this case, the rectangle has two sides measuring 9x + 9, and two sides measuring 4x - 3.
So, the expression representing the perimeter would be the sum of these four side lengths:
(9x + 9) + (9x + 9) + (4x - 3) + (4x - 3)
To simplify, you can combine like terms:
9x + 9 + 9x + 9 + 4x - 3 + 4x - 3
Combining like terms, the resulting expression is:
(9x + 9x + 4x + 4x) + (9 + 9 - 3 - 3)
Simplifying further, you get:
26x + 12
So, the correct expression representing the perimeter of the given rectangle is 26x + 12.
perimeter= 2(L+W)=2(9x+9+4x-3)
= 26x+12
