Classify the following polynomials according to the number of terms. Combine any like terms first.

1. x^2 +5x = binomial

2. x^3 + 3x^2 = binomial

3. 4x^3 + -x + x^2 = trinomial

4. 0? monomial? none

x^2 + 3x + 2x

x^2 + 5x = Binomial

x^3 + x + 3x^2 - x

x^3 + 3x^2 = Binomial

4x^3 + x + x^2 - 2x

4x^3 + x^2 - x = Trinomial

3x^4 + x - 3x^4 - x

0 = No Polynomial/Zero Polynomial

Hope this helps!

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
