EzraThe two numbers that add up to 21 and multiply to 90 are 9 and 12. This is because 9 + 12 = 21 and 9 * 12 = 108. To find the correct numbers, you can set up a system of equations where x + y = 21 and x * y = 90. By solving these equations simultaneously, you will find that x = 9 and y = 12.

What two numbers add up to -14 and are factors of -189?
Pairs of numbers whose sum is -14 and that are factors of -189 include -7 and -7, and -21 and 7.
What factors of a number equal 21?
When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.
What two numbers have 105 as their LCM?
The two numbers that have 105 as their least common multiple (LCM) are 15 and 7. This is because the LCM of two numbers is the smallest number that is a multiple of both numbers. In this case, 15 and 7 are both factors of 105, and no smaller number can be a multiple of both 15 and 7.
What times what 441?
Each of these factor pairs (multiply the numbers in parentheses) equals 441: (1, 441) (3, 147) (7, 63) (9, 49) (21, 21)
What two numbers have a LCM of 21?
3 and 7, among others.
