8 and -8
5 and 10
Hard question
8 and 4, added together and multiplied by 7
A number multiplied by itself added to itself equals 30. What are the two possible numbers?
511
When added? multiplied?
No two numbers exist.for the two numbers to be added to be negative and multiplied to be positive, both numbers must be negative, and the highest possible multiplication for two numbers added to -12 would be (-6 and -6) but multiplied, yields 36. So, no such numbers would exist.
5+5 By quadratic equation the two numbers (roots) are: 8.872983346 and 1.127016653 Added together = 10 Multiplied = 10
There are infinitely many answers. 1 and 325 (multiplied), or 1 and 324 (added) are two examples.
The two numbers are 6 and -5. 6 x (-5) = -30, 6 + (-5) = 1.
