Answer:
For
, Leading coefficient is -2, Degree is 2, Constant term is 0
For
, Leading coefficient is -25, Degree is 2, Constant term is 9
For
, Leading coefficient is 1, Degree is 5, Constant term is -1
Step-by-step explanation:
Given:
Polynomials:

To find: leading coefficient, constant term and degree
Solution:
Leading coefficient is the coefficient of the variable with the highest power.
Degree is the highest power of the variable.
The term of degree 0 is the constant term of a polynomial.
For

Answer:
10 months
Step-by-step explanation:
22x+80=30x
subtract both sides by 30x
-8x+80=0
then subtract 80 from both sides
−8x=−80
divide both sides by -8
x=10
