What are the instructions? If it just says to classify it, there is no degree, so it would be a binomial.
Here is a chart;
1 term = monomial. Example; 6x
2 terms = binomial. Example; 6x + 5
3 terms = Trinomial. Example; 6x + 5 + 2y
4 terms = polynomial of 4 terms. Example; 6x + 5 + 2y + 2x^3
It would be 20 because the highest number is 25
Answer:

Step-by-step explanation:
As given
if n erasers have a weight of 80 grams .
I.e
n erasera = 80 grams.
1 erasers weight .

Now find out the weight of the 50 erasers.

Simplify the above


Distance around a circle is CIRCUMFERENCE
DIAMETER*PI=CIRCUMFERENCE
