# What multiplies to 6 and adds to 18?

There are no two numbers that multiply to get 6 but add to get 18. In fact, the solutions are:

- 1x1x1x1x1x1x1x1x1x1x1x1x6 = 6; 1+1+1+1+1+1+1+1+1+1+1+1+6 = 18
- 1x1x1x1x1x1x1x1x1x1x1x1x1x2x3 = 6; 1+1+1+1+1+1+1+1+1+1+1+1+1+2+3 = 18

### What multiplies to 5 but adds to 6?

The numbers are 1 and 5 because 1 times 5 = 5 and 1+5 = 6

### What multiplies to 70 and adds to -12?

There are no two real numbers that will, but the following complex numbers do: (-6 + i√34) & (-6 - i√34)

### What adds to 7 and multiplies to -6?

It cannot be done, I'm assuming you're factoring - try using the quadratic formula

### What adds to 9 and multiplies to 36?

The factor pairs of 36 are (36, 1) (18, 2) (12, 3) (9, 4) (6, 6) None of them add up to 9. If that was -36, you could use 12 and -3

### What number adds to -3 but multiplies to -6?

-12 does. -- When added to 9, it becomes -3 . -- When multiplied by 1/2 , it becomes -6 .

### What is a number that multiplies to -50 and adds to -20?

No single number multiplies to -50 and adds to -20. There is no indication in the question as to how many numbers you are interested in.

### What multiplies to get -72 and adds to get -18?

Different signs show it would have values subtracted to get the 18. 1,72=71 2,36=34 3,24=21 4,18=14 6,12=6 8,9=1 There are none that work so if you are factoring then it would be prime.

### What is the rule in comparing a set of fractions?

the top adds what the bottom adds. the top subtracts what the bottom subtracts. the top divides what the bottom divides. the top multiplies what the bottom multiplies.
