Answer 7

Write the polynomial 4x2 + x5 – 12 + 6x in standard form.

A.
–12 + 6x + 4x2 + x5

B.
x5 + 4x2 + 6x – 12

C.
x2(4 + x3) + 6(x – 2)

D.
4x2 + x5 – 12 + 6x

Answer 8

To put polynomials in standard form, you put them in decending order by the exponents, so it should look like this: x^5+4x^2+6x-12

Answer 9

sorry i went afk

Answer 10

i have a few more

Answer 11

Which expression is a polynomial?

Answer 12

i keep failing at this one this is a different hw problem btw

Answer 13

i don't like online homework

Answer 14

With those four answers, A. is the only one that will work because polynomials cannot have any dividing by a variable (like in answers B. and C.) A polynomial also cannot contain the square root of x because that is a fractional exponent.

Answer 18

Express the perimeter of the triangle as a polynomial.



A.
–11x – 5

B.
11x – 4

C.
11x + 4

D.

Answer 19

For this one you need to add together the like terms so 4x+x+6x=11x and 1+2-7=-4, and our final answer would be 11x-4
