They are -3 and -5
-13
8, 5 and 2
any 2 numbers can be multiplied together. eg. 2x1 is 2. 5x91000 is 455000
2*3*-5 = -30 3*-5 = -15 -5 - 5 - 3 - 2 = -15
15 and -3
They are: 1*3*5 = 15
16 and 15
The factor pairs of 45 are: 1 × 45 3 × 15 5 × 9
1 & 75 3 & 25 5 & 15 are the factor pairs of 75.
These pairs of numbers, when multiplied, equal 90: (1, 90) (2, 45) (3, 30) (5, 18) (6, 15) (9, 10)
There are only two numbers that can be multiplied to make 15. These numbers are 3 and 5. This is true because 3*5 = 15
