This question is worth 20 points and I will mark brainliest which expressions are equivalent to 2 (3h + 7) choose "equivalent" or "Not equivalent" for each expression.

6h+7

2+3h+7

6h+7+7

3h+3h+14

(3h+7) + (3h+7)

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.
