Answer:
C, 4x²y² + 5x + 1
Step-by-step explanation:
to solve, we can first factor the numerator by finding a GCF.

the GCF of the numerator would be 6xy, as each term can be divided by 6xy. we have the following:

we can cancel out the numerator and the denominator as both contain 6xy so we have the following:
4x²y² + 5x + 1
we cannot simplify this any further, so our answer is C
The anwers is B hope it helps please give me Brainly
Well for the first one the ratio would be 12:6 I believe
If you want to keep it technical, the normal “/unit rate” for running is minutes per mile. You can use dimensional analysis like I did below to find the answer. You should get 11.45 min/mile or about 11 min 25 sec per mile
