For #12, they are vertical angles so 4x=84 degrees. Therefore you take 84 and decide by 4 and you get what x is (it’s 21)
I think it’s 20d-$12
Hope this helps!
Answer:
(1 +5t )(1 + 5t)
Step-by-step explanation:
1 +10t +25t^2
1 + 5t + 5t + 25t^2
(1 +5t) + 5t(1 +5t)
(1 +5t )(1 + 5t)
What line? Please attach a picture or something, so we can figure out the equation for you.
