Question

what is the perimeter of this parallelogram? 10x + 8 6x² - 9x - 45 5x + 4 9x

Explanation:

Step1: Recall perimeter formula for parallelogram

The perimeter \(P\) of a parallelogram with adjacent - side lengths \(a\) and \(b\) is \(P = 2(a + b)\). Here, \(a=3x + 9\) and \(b = 2x-5\).

Step2: Substitute side - lengths into formula

$$
LATEXBLOCK0
$$

Step3: Expand the expression

$$
LATEXBLOCK1
$$

Answer:

\(10x + 8\)
