The first step in the process for factoring this trinomial x^2-3x-40 is to? ?
a. list all the factors of 40
b. find the sum of the factors of 40
c. list all the factors of 3
d. find the sum of the factors of 3

A

Step-by-step explanation:looking at the rule PEMDAS you see that the first thing you should do is A

the answer is (-4,-4)

hope this ! : d

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
