Answer=C 2 1/2
(12 1/2)÷5=2 1/2
or
12.5/5=2.5=2 1/2
Your answer is 3x^(2)+3x+6
Hope this helped!
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
