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

well what did you do it matters what you did : )

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
