Well, you could start by finding out what that sum is: 36 + 64 = 100 .
Then, knowing the sum, you can go ahead and multiply 20 by it: 20 x 100 = 2,000 .
A somewhat more formal approach might look like this:
20 (36 + 64) = (20 x 36) + (20 x 64) = (720) + (1,280) = 2,000
36 and 64
36 and 64
The GCF is 4.
64 and 36.
How about: 36+64 = 100
62 + 82 = 36 + 64 = 100
They are 36 and 64
They are 36 and 64
They are: 36 and 64
28 and 36
4x(7+9)= 28+36=64.
Square the numbers and then add them together. Example: 62 + 82 = 36 + 64 = 100
