What is -3(2x-4)+9x-8

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
