Question

If you multiply two integers together and then add 4, the result is 40. Which of the following could NOT be the sum of the two numbers?
- 12
- 13
- 15
- 18
- 20

Answer 1

Answer:

18

Step-by-step explanation:

xy + 4 = 40

xy = 40 - 4

xy = 36

What two numbers can b multiplied to give 36? Then add them.

9 + 4 = 13

18 + 2 = 20

6 + 6 = 12

12 + 3 = 15

The odd option is 18
