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

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
