Answer:
interval 41-50 and 61-70 i think
Step-by-step explanation:
Its letter D
7(19)-21 (x=19)
133-21=112 (RZ)
112+112=224 (RT)
4(5)=20
5(5)=25

(x^2-5)(3x-1)
Here's how I got this answer:
I found the GCF for each part of the polynomial.
3x^3 and -15x both contain 3x, and -x^2 and 5 share -1.
I then can divide the polynomial by 3x-1, and I get x^2-5
(Okay, that's not what I really did, but I can solve these on sight and don't remember the proper way to do it.)
