Answer:
9^5
Step-by-step explanation:
So easy
so driscoll has 9 reports to grade and each page has 6 pages.
just multiply 9 and 6 which gives you your answer 54.
so out of 54, he has graded only 12 pages which means that you need to subtract.

driscoll has 42 pages left to grade.
you can recheck your answer by adding 42 ans 12 which gives your answer as 54. so yup our answer is right.
The given angles are =
(x+40)° and 3x°
As the given angles are opposite to each other on the intersecting lines, so they are vertical angles. These are congruent or equal.
So, 


Hence x = 20°
The given angles are =
(x+40) = 20+40 =60°
3x = 3*20 =60°
A ?
Might wanna double check though
