Number one is but number two is not
of more than 1 dot is on an “up and down” line then it’s not a function
83-63=20
So your answer is 20
We will have to use the formula for the area of a trapezoid on this problem, which is (
and
are the bases of the trapezoid and
is the height):

All we need to do is substitute the information we are given into our formula:

Now, let's just simplify the equation:




The missing base has a length of 13 units.
4 (points for an A) x 21 (As) = 84
3 (points for a B) x 24 (Bs) =72
2 (points for a C) x 15 (cs) = 30
84 + 72 + 30 = 186 (total points)
186 divided by 60 (total credits) = 3.1
