Ineed some expression ! : add 9 to b, then multiply c by the result

The expression to represent the verbal equation is

(9 + b)c

Adding parenthesis isolates the addition saying that it must be done first.

Hope this helps! <3

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
