I don't know but if I were to guess I'll pick C. Hope this helps
I think you mean x^2 - 7x + 8
This is a basic factoring problem:
What two numbers multiply to make 8 and add to make -7?
There are no two numbers that work!
Therefore, it is prime
For this case, the first thing we must do is define a variable.
We have then:
c: the number of classes
We write now the inequality that represents this problem:
8c + 12 <= 154
Answer:
An inequality that represents the number of classes. c, that Theo can take is:
8c + 12 <= 154
