Question

The perimeter of the rectangle when x = 3 is 22. Which equation can be used to represent the perimeter of the rectangle, P(x)?

P(x) = 2(f ∙ g)(x)
P(x) = (f ∙ g)(x)
P(x) = 2(f + g)(x)
P(x) = (f + g)(x)

Answer 1

P(x) = 2(f+g)(x)

Explanation:

perimeter of the rectangle = 2( length + width )
