Find the difference of the polynomials given below and classify it in terms of degree and number of terms. 3n2(n2 + 4n – 5) – (2n2 – 14 + 3)
OA. 3rd degree polynomial with 4 terms
OB. 4th degree polynomial with 4 terms
OC. 3rd degree polynomial with 5 terms
OD
4th degree polynomial with 5 terms

Given:

The polynomial is:

To find:

The difference of the polynomials and classify it in terms of degree and number of terms.

Solution:

Consider the polynomial,

On simplification, we get

The degree of this polynomial is 4 and the number of terms is 5.

Therefore, the correct option is D.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
