PL HELP M 5.Multiply to give you -80 and adds to give you -2 and

6. Multiply to give you -15 and adds to give you -14 and

7. Multiply to give you -36 and adds to give you 0 and

8. Multiply to give you -48 and adds to give you -8 _ and

To figure these out, write out the factors of each number you multiply to. Then, go down the list of factors and see which two numbers add to give the 2nd number.

Factors of -80:
-1 80 : 80+ -1 = 79
1 80 : 80 + 1 = 81
2. -40 : -40+2 = -38
-2 40 : 40 + -2 = 38
4 -20 : 4 + -20 = -16
-4 20 : -4 + 20 = 16
5 -16 : 5 + -16 = -11
-5 16 : -5 + 16 = 11
8 -10 : 8 + -10 = -2

8 x -10 = -80 and 8 + -10 = -2 so 8 and 10 is your first answer

Factors of -15:
-1 15 : -1 + 15 = 14
1 -15 : 1 + -15 = -14

1 x -15 = -15 and 1 + -15 = -4 so 1 and -15 is your second answer.
I didn’t write any more factors because I already got the answer.

Try 7 and 8 on your own and let me know if you are stuck/don’t understand anything.
I hope this helps :)

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
