A) For the polynomial y=x^7(x+5)(4x-6)(7-x)
State the degree=
and the number of terms=

*I got
State the degree=6
and the number of terms=8
however it says im wrong

B)For the polynomial y=4x^5+6x^9+7x^2+9x-9
the number of terms=
*I got
the number of terms=17
however it says im wrong

I am afraid you are wrong
Polynomial (x+5)(4x-6)(7-x) degree is 3
When you multiply par x^7 the degree becomes 10

you need a lesson ...

Polynomials: Definitions / Evaluation

A) equals to:
so the degree is 10 and it has 4 terms.
B) it has 5 terms.
