Simplify the given polynomial and use it to complete the statement.
Lorico [155]

Answer:

1)  2x^{2}+13

2) Option C.

3) Option B.

Step-by-step explanation:

1. You must apply the Distributive property as following:

(-5x^2-2x+4)+(8x^2-x-1)-(x^{2}-5x+2x-10)

2. Now, you must distribute the negative sign, then you have:

-5x^2-2x+4+8x^2-x-1-x^{2}+5x-2x+10

3. Finally, you must add the like terms. Then you obtain the polynomial:

2x^2+13

4. By definition, a polynomial that has two terms is classified as a binomial. Therefore, the answer is the option C.

5. The degree of a polynomial is determined by highest exponent of the variable. So, it is a polynomial of degree 2 (option B).

11Alexandr11 [23.1K]

Answer:

2.46×10^8

Step-by-step explanation:

The decimal point is here

246000000.

Then it must be moved up to here

2.46000000

Those are eight steps from where it was, so to compensate and make sure the number remains the same remove the zeros and multiply by 10^8

Then you have

2.46×10^8
