Answer:

21x - 42, see below :)

Step-by-step explanation:

Hello!

We know that f(x) is equal to 3x - 6

We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6

7 * f(x)

7(3x-6)

We use distributive property to open the parenthesis:

7 * 3x + 7 * -6

21x - 42

A pair of parallel lines is cut by a transversal. What are the measures of the two marked angles?

VMariaS [17]

Answer:

○ A. $\displaystyle 56°\:and\:56°$

Step-by-step explanation:

Since these two angles are alternate interior angles, we set both expressions equal to each other:

[−6x + 20]° = [−8x + 8]°

+ 6x - 8 + 6x - 8

_________________

$\displaystyle \frac{12}{-2} = \frac{-2x}{-2} \\ \\ -6 = x$

Plug this back into both expressions above to get 56° each.
