Answer:

  • D. A = x² + 44x = 808

Step-by-step explanation:

Check if the relationship is linear. Verify the difference between areas.

We can see the difference is not common.

It means we can exclude options B and C.

The remaining options are quadratic (A and D).

<u>Try the last column with option A:</u>

  • 4813 = 45² + 1908
  • 4813 = 3933
  • False

<u>Verify the last option:</u>

  • 4813 = 45² + 44*45 + 808
  • 4813 = 4813
  • Correct

We can check and confirm the other columns are correct as well.

Classify the polynomial 5m^10
Naily [24]

Answer:

Monomial

Step-by-step explanation:

A polynomial has terms in their equation.

When it is a trinomial, it usually follows the pattern such as x^2+2x+1.

When it is a binomial, it usually is something like x+2

...And finally, when it is a monomial, it can be anything that has just one term. So let's say 4x^8883293483.

The polynomial 5m^10 classifies under a monomial since it only has one term
