A rectangle has a length represented by the function f(x) and a width represented by g(x).

Which statement describes the combined functions P(x) and A(x)?
A. A(x) is linear, but P(x) is not.
B. P(x) is linear, but A(x) is not.
C. Both P(x) and A(x) are linear.
D. Neither P(x) nor A(x) are linear.

a is the right answer

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
