Multiply -1 (the - sign is equal to -1) to both numbers in the parenthesis.
-1 * 3x = -3x
-1 * -8 = 8
So now the equation looks like....
10x - 3x + 8
Now combine like terms.
10x - 3x = 7x
7x + 8 is the answer.
**I had a hard time reading what you wrote there because it was not really that clear. Perhaps giving me a screen shot next time would make it easier for me. Thanks!
2) Corresponding angles of parallel lines cut by a transversal are congruent.
3) Vertical angles are congruent.
4) Transitive Property. If angle 2 is congruent to angle 6 and angle 4 is congruent to 2, then angle 6 is congruent to angle 4.

<u>Step-by-step explanation:</u>
Given: cos 330 = √3/2
Prove that tan (165) = √3 - 2
We can work out the first three terms of this quadratic equation with substitution.
The first term of this sequence is where n=1, we can substitute 1 in for n
y=1^2+2(1)-4
y=1+2-4
y=-1
We can do this for the next two terms as well
y=2^2+2(2)-4
y=4+4-4
y=4
For the last term:
y=3^2+2(3)-4
y=9+6-4
y=11
