<h3>
Answer: Choice C. (x+1)(x-5)</h3>
We need to find two numbers that
- Multiply to -5 (last term)
- Add to -4 (middle coefficient)
Through trial and error, those two numbers are 1 and -5
- 1 times -5 = -5
- 1 plus -5 = -4
So this means x^2-4x-5 factors to (x+1)(x-5)
This is the same as (x-5)(x+1) since the order of multiplication doesn't matter.

Answer:
Step-by-step explanation:
n^2-7n is n(n-7). So n(n-7) = 0. We know n can be zero because 0* anything is 0. It could also be 7 because we are looking to multiply by 0. So to get a zero in the parentheses. you would do 0+7. Which is obviously, 7
Answer:
30244
Step-by-step explanation:
I think you divide 20 and 8 ... I just took a wild guess, I'm not the best at shape/figure questions, so I'm really sorry.
Hopefully that helped! :)
