First, you’d look at what can multiply together to make 20. You can multiply 10x2, 1x20, or 4x5 (or change them so each number is a negative) to make a positive 20. You then must look at which one of these can be added or subtracted together to create -9. Negative 4 and 5 can be subtracted to make -9, so you would factor them out, as well as the x^2, and get the answer (x-4)(x-5).
Answer: (x-4)(x-5)
Answer:
79
Step-by-step explanation:
Let's say that N is the number of cards.
So the first step is N+5, because dan bought 5 new cards.
Next his dog ate half the collection, so the 2nd piece of the problem is
The last step is to now make it an equation. Because there are now 46 cards left, =42.
Now solve for N which is N+5=84=> N=79
