Rewrite the expression 12x + 8 to find an equivalent expression. Show three possible
expressions. What do the rewritten expressions
tell you about the relationships among the
quantities?

12(x + 8)  8(x + 12)  and x( 12 + 8) all equal to 20x

Step-by-step explanation:

find the magnitude of the trig term
