Algerba :)) pls help

The first one is B, the second is A

Step-by-step explanation:

For a polynomial to be in standard form, it needs to have the exponents decreasing from left to right. In order from left to right, B goes 7,3,2,1,0, hence it is in standard form.

A polynomial cannot have a fractional exponent, hence a is not a polynomial.

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
