Factor the expression completely.

54 + 45x

9(6+5x)

Step-by-step explanation:

54 + 45x (Write out the original equation in standard form. This has already been done.)

=9(6) + 9(5x) (For this step, you rewrite 54 as 9(6) and 45 as 9(5).

=9(6+5x) (For this step, you factor out 9 because it is the greatest common denominator.)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
