So let's break this question down.
You need a bit of both, right? Well we need to calculate how many multiple choices we can do whilst having true/false questions, and not going over or under on points.

So, let's pick a random number, 5. So let's do 8x5, that equals 40.

Ok so now we have our number, 5 multiple choice questions. 
The true/false questions should be easy, just do 3x20 and you get 60.

Name the binomial you can multiply by (x + 9) to get the product x^2 + 5x- 36
SpyIntel [72]
If you would like to solve (x^2 + 5x - 36) / (x + 9), you can do this using the following steps:

a = ?
(x + 9) * (x + a) = <span>(x^2 + 5x - 36)
x^2 + ax + 9x + 9a = x^2 + 5x - 36
ax + 9x = 5x
a + 9 = 5
a = 5 - 9 
a = - 4

The correct result would be x - 4.
