To find factors that multiply to 120 and add up to -7, we can use algebra. Let's denote the two factors as x and y. We know that xy = 120 and x + y = -7. By solving this system of equations, we can find that the factors are -15 and -8.
Well, isn't that an interesting puzzle we have here! Let's take a moment to appreciate the beauty of numbers coming together. To find two factors that multiply to 120 and add up to -7, we can think of the numbers -15 and -8. Remember, there are always solutions waiting to be discovered in the world of mathematics.
This only works if it's -120. Then the answer is -15 and 8
15 and 4 are the factors of 120 that add up to 19.
The factors of 21 that add up to 8 are 1 and 7.
factors of 30 that add to 17 are 2 and 15
No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime
