The answer that I would choose would be C.
65:100 because there are 65 girls and then 65 girls + 35 boys = 100 total students
First, find out how much ribbon there is.
3 x 12 = 36
Now, see how many times you can divde that by 8.
36 can only be divided by 8 four times, and there would be 4 inches of ribbon left.
So, you would be able to make 4 bows, with 4 inches of ribbon remaining.
A polynomial with no odd-degree terms will have a graph with even symmetry. The one here that qualifies is ...
c. 7x^4 +9x^2 -12
If you are solving for x than the answer would be x=4.
