Choose the correct classification of 2x + 10x2 − x3 by number of terms and by degree. third degree trinomial fourth degree trinomial sixth degree polynomial first degree binomial

3 terms, third degree polynomial

the polynomial has 3 separate terms 2x, 10x² and - x³

The degree of a polynomial is determined by the term with the largest exponent, given the polynomial in standard form

that is : - x³ + 10x² + 2x

the largest exponent is 3 , hence third degree polynomial

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
