To get roots of 13 and -3 the simplified equation will have to look like this.
(X-13)(X+3)=0
So if we multiply this out with foil method we get this:
X^2 -10X -39
So the answer is A
8x + 2x
Plug the variable in.
8×6 + 2×6
48+12 = 60
Answer:
B 
Step-by-step explanation:
Formula of straight line in Point slope form

Here

therefore equation of line having slope 5 and passing through point )1, 9) is given as

Seven fewer than a number is n-7
The common difference of the data set of A is 1. While the common difference in the data set of B is 0.80
B.) 3.8 + 0.80 = 4.60
4.6 + 0.80 = 5.40
5.4 + 0.80 = 6.20
6.2 + 0.80 = 7.00
