The table shows the functions representing the length and width of a rectangle. 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)

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

sounds & other waves originate from any vibrating object
