Simplify by finding the product of the polynomials below. Then Identify the degree of your answer. When typing your answer use t

nexus9112 [7]

Solution:

Given:

$(2x^2+2x+1)(4x-1)$

To get the product of the polynomial; we use the distributive property of multiplication.

$a(b+c)=ab+ac$

$\begin{gathered} (4x-1)(2x^2+2x+1) \\ 4x(2x^2+2x+1)-1(2x^2+2x+1) \\ =8x^3+8x^2+4x-2x^2-2x-1 \\ \text{Collecting similar terms together and simplifying further;} \\ =8x^3+8x^2-2x^2+4x-2x-1 \\ =8x^3+6x^2+2x-1 \end{gathered}$

Therefore, the product of the polynomials is;

$8x^3+6x^2+2x-1$

If f(x) = 7x- 3 and g(x) = x2 - 4x- 8, find (f+ 9%).

zavuch27 [327]

Answer:

option D

Step-by-step explanation:

f(x) = 7x- 3

g(x) = x2 - 4x- 8

we have

(f+g)(x)= 7x- 3 +x2 - 4x- 8

(f+g)(x)= x2+ 3x- 11

Sydney is playing a game on a map with a marked grid. To start, she places a game piece at (1, 4). She moves 3 units east and 2

Anastasy [175]

Answer:

(7, 8)

Step-by-step explanation:

If Sidney places each piece 3 units east and 2 units north of the last one, we can figure out which coordinate comes first by subtracting the position of the second piece (S) by the position of the first piece (F):

$S - F = (4,6) - (1,4) = (3,2)$

We can conclude that coordinates are in the (East, North) format.

Therefore, the location of the third piece (T) is:

$T = S(E,N) +(3,2)= (4,6)+(3,2)\\T = (7,8)$
