The area of a room is 396 square feet. the length is (x + 8) feet and the width is (x + 4) feet. find the dimensions of the room. you only need to find the length and width.

L:18ft

Hope it helps

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
