The table shows the functions representing the length and width of a rectangle. Width g(x) = x + 2 1 2 3 Length f(x) = x + 3 4 5 6 7 5 6 4 The perimeter of the rectangle when x = 3 is 22. Which equation can be used to represent the perimeter of the rectangle, P(x)? O P(x) = 2(fºg)(x) O P(x) = (f. g)(x) OP(x) = 2(f + g)(x) P(x) = (f + g)(x) ​
