Answer:
I think it is 28%
Step-by-step explanation:
.7*.4=.28
The answer is quintic binomial.
It is quintic because its highest power is 5. Quartic would mean its highest power is 4.
It is a binomial because the two terms are -4x^5 and -6x^3. Terms are separated by + or - signs.
Simplifying it would make it 3/4b^2. I can't write it down the correct way, but it's three over four times b squared. Unless it's a square root, then things would be different.
