First, add two plus ten together. That number is 12. Then do the opposite function that you did earlier, which would be multiplying by 3. 12 times 3 is 36, so the answer is 36.

There are no such numbers. The only two numbers that sum to 12 and whose product is -84 are irrational, and so cannot be considered as factors of 84.

To solve this, set the denominators equal to one another so that we can just add the numerators. two fourths becomes 6/12 and two sixths becomes 4/12 When you add fractions with the same denominator, just add the numerator. The denominator stays the same This will leave you with 10/12, which can be simplified to equal 5/6

The two numbers that multiply together to equal 48 and add together to equal 19 are 12 and 4. When multiplied, 12 × 4 equals 48, and when added, 12 + 4 equals 16. Since these numbers do not satisfy both conditions, the correct pair is actually 16 and 3. They multiply to 48 and add up to 19.
The only number that equals 32 is 32, and it's not a factor of -12 .
