Use the remainder theorem to find the remainder of 2x^4 + x^2 - 10x -1 divided by x +2.
I am Lyosha [343]

Answer:

The remainder is 55

Step-by-step explanation:

Let

p(x)= 2 {x}^{4}  +  {x}^{2}  - 10x - 1

According to the remainder theorem, if p(x) is divided by x+a, the remainder is p (-a).

The given divisor is x+2, therefore the remainder is given by:

p( - 2)

We substitute x=-2 to get:

p( - 2)= 2 {( - 2)}^{4}  +  {( - 2)}^{2}  - 10( - 2) - 1

We simplify to obtain:

p( - 2)= 2  \times 16 +  4  +  20- 1

We multiply to get:

p( - 2)=3 2  +  4  +  20- 1 = 55

Therefore the remainder is 55

Answer:

The slope of function A is 2 times the slope of function B.

FinnZ [79.3K]

Answer:

97

Step-by-step explanation:

For this equation we have to plug in, so z= 6 and w=7. the question is 8z+7w

so plug in 6 for z and 7 for w. 8(6)+7(7) so 8*6 is 48 and 7*7= 49. 48+49= 97

hope this helps :)
