fourth degree trinomial.

Step-by-step explanation:

we have

Classify the polynomial

Remember that

Polynomials can be classified two different ways - by the number of terms and by their degree

1. Number of terms.

In this problem we have tree terms . so is a trinomial

2. Degree.

The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

In this problem the highest exponent is the so this is a fourth degree trinomial.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
