Answer:
The GCF is going to be 30
Step-by-step explanation:
This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here
The prime factorization of 21, 2 × 3 × 3 × 5= 90
The prime factorization of 28, 2 × 3 × 5 × 7 = 210
The common factors are, 2, 3, and 5. We multiply those to get the GCF.
2 × 3 × 5 = 30
Answer:
It would be

Answer:
The third one!
Step-by-step explanation: 5 5 5 5 its 5!
Well I would say multiply 16*4 to get 64 so unless you want to answer it, the answer is (-5*64) is your simplified equation. ()- is just to separate from the words
* - is multiply symbol. This is much more useful when using variables so your X variable don't get mixed up.
