Answer:
-1 and -30 -1+-30=-31
-2 and -15 -2+-15=-17
-3 and -10 -3+-10=-13
-5 and -6 -5+-6=-11
-6 and -5 -6+-5=-11
-10 and -3 -10+-3=-13
-15 and -2 -15+-2=-17
-30 and -1 -30+-1=-31
30 and 1 30+1=31
15 and 2 15+2=17
10 and 3 10+3=13
6 and 5 6+5=11
5 and 6 5+6=11
3 and 10 3+10=13
2 and 15 2+15=17
1 and 30 1+30=31
Step-by-step explanation:
A factor is a number that can be evenly divided by another number without a remainder or decimal. These numbers can all be divided by 30 without resulting in a remainder. After we find the corresponding factor (by dividing by 30), we add them in the resulting column.
