Question

PLEASE HELP i need to get a good grade on this andi need to get themall correct please
1. Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms.

8x + 5x3 – 5 (1 point)5x3 + 8x – 5; cubic trinomial
8x – 5 + 5x3; not a polynomial
5x3 + 8x – 5; quadratic binomial
8x + 5x3 – 5; fourth-degree monomial

2. Simplify the sum.

(4u3 + 6u2 + 7) + (6u3 – 2u + 7) (1 point)14 – 2u + 6u2+ 10u3
10u3 + 6u2 – 2u + 14
–2u3 – 2u2 + 6u – 14
–2u3 + 6u2 – 2u + 14

3. Simplify the difference.

(6w2 – 5w – 8) – (7w2 + 4w – 2) (1 point)13w2

Answer 1

–w2 – w – 10
13w2 – w – 10
–w2 – 9w – 6

4. Factor the polynomial.

48w7 + 30w4 (1 point)6w4(8w3 + 5)
6w3(8w4 + 5w)
w4(48w3 + 30)
6(8w7 + 5w4)

5. Simplify the product using a table.


–3

–4

(1 point)




6. Simplify the product using FOIL.

(1 point)




7. What is a simpler form of each product?

(2x – 6)2 (1 point)4x2 – 24x + 36
4x2 – 8x + 36
4x2 + 36
4x2 – 12x + 36

8. What is a simpler form of each product?

(1 point)




9. What is a simpler form of the following expressions?

(j + 7)(j – 7) (1 point)j2 + 14j – 49
j2 – 14j – 49
j2 + 14j – 49
j2 – 49

10. What is a simpler form of the following expressions?

(7p – 8)(7p + 8) (1 point)49p2 + 112p + 64
49p2 – 112p – 64
49p2 + 64
49p2 – 64

Answer 2

will give medal and become fan

Answer 3

\[8x + 5x^3 – 5 =x^3 + 8x – 5;\] cubic trinomial is true

Answer 4

how about one at a time, much easier to answer that way

Answer 5

ok

Answer 6

do u have all the answers i need them im behind cuz im in the hospital could u please help
