Answer:
a. 16x + 9x + 8x + 11
b. 33x + 11 (or 11(3x + 1) if this is asking for a factored expression)
Step-by-step explanation:
Looking at the directions, part a tells us to use all 4 side lengths, so the equation for part a is 16x + 9x + 8x + 11.
Now to simplify that expression.
16x + 9x + 8x + 11
Step: Combine 16x, 9x, and 8x. I'll go from left to right.
25x + 8x + 11
33x + 11
(What you see above this statement is my answer, but work is below if this is asking for a factored expression.)
11: 1, 11
33: 1, 3, 11, 33
Now divide both 33x and 11 by 11 and put the 11 outside the parentheses.
33x/11 = 3x
11/11 = 1
11(3x + 1)
