What numbers when added together equal -16 but when multiplied equal 64?
-8 and -8
What numbers that when multiplied equal 48 but then when added equal 16?
64
How do you factor x2 16x plus 64?
to factor (x2-16x+64), you need to find two number whose product is 64 and whose sum is 16. These two numbers are 8 and 8. (x2-16x+64)=(x-8)(x-8)
What two prime numbers equal 64?
The sum of the prime numbers 11 and 53 equals 64.
What two numbers when added equal 6 and a half and when multiplied equal 64?
This problem actually has no solution. Any two numbers that will add to 6.5 will be too small to produce a multiple equal to 64. However, for problems like this in general, writing the question as a formula might help you solve it. 1. Assume the numbers are x and y. 2. Write two equations (two unknowns and two equations gives you enough information to solve). -The first part, "two numbers added equal 6.5" can be written as x + y = 6.5 -The second part, "two numbers multiplies equal 64" as xy = 64 3. Manipulate the equations to solve. For example: y = 64/x x + y = x + (64/x) = 6.5 4. Solve for x, and then use x to find y using either of the original formulas.
