about 33 times or 33.5 times exactly
33 (33.3333) times.
3x2 times x-33 can be simplified to: 3x3 times -27

To square a number means to multiply it by itself. In this case, 332 (which you read: 33 squared) = 33 x 33.

49- 16 = 33. 49is 7 squared, and 16 is 4 squared.
Well, let's see here, my friend. If we take 700 and divide it by 21, we find that it can go in 33 times without going over. Isn't that just a happy little discovery? Remember, there's no mistakes in math, just happy little accidents.

The GCF of 33 and 21 is 3.
-8 × (number + 21) = 96 → number + 21 = 96 ÷ -8 → number = 96 ÷ -8 - 21 = -12 - 21 = -33
33 and 21 are composite. So is 3321.
