Answer:

(A) 6x³+8x² + 4x - 4, but only if my change is correct to 6x³5x² - 2 is correct.

Step-by-step explanation:

Is "g(x) = 6x³5x² - 2" meant to be g(x) = 6x³-5x² - 2?

If so, (f+g)(x) = 3x² + 4x - 6 - (6x³-5x² - 2)

(f+g)(x) = 3x² + 4x - 6 - 6x³+5x² + 2

(f+g)(x) = 6x³+8x² + 4x - 4

(A)

PLEASE ANSWER QUICKLY ASAP ANSWER QUESTION A AND B

Evgen [1.6K]

Answer:

a) $a+b+c=\begin{pmatrix}-2\\-3\end{pmatrix}$

b) (i) $a+2c=\begin{pmatrix}-4\\2\end{pmatrix}$

(ii) $k=2$

Step-by-step explanation:

It is given that,

$a=\begin{pmatrix}4\\-10\end{pmatrix},b=\begin{pmatrix}-2\\1\end{pmatrix},c=\begin{pmatrix}-4\\6\end{pmatrix}$

We need to find the value of a+b+c.

$a+b+c=\begin{pmatrix}4\\-10\end{pmatrix}+\begin{pmatrix}-2\\1\end{pmatrix}+\begin{pmatrix}-4\\6\end{pmatrix}$

$a+b+c=\begin{pmatrix}4+(-2)+(-4)\\-10+1+6\end{pmatrix}$

$a+b+c=\begin{pmatrix}-2\\-3\end{pmatrix}$

(i) We need to find the value of a+2c.

$a+2c=\begin{pmatrix}4\\-10\end{pmatrix}+2\begin{pmatrix}-4\\6\end{pmatrix}$

$a+2c=\begin{pmatrix}4\\-10\end{pmatrix}+\begin{pmatrix}-8\\12\end{pmatrix}$

$a+2c=\begin{pmatrix}4+(-8)\\-10+12\end{pmatrix}$

$a+2c=\begin{pmatrix}-4\\2\end{pmatrix}$

(ii) It is given that a+2c=kb, where k is an integer. We need to find the value of k.

$a+2c=k\begin{pmatrix}-2\\1\end{pmatrix}$

$\begin{pmatrix}-4\\2\end{pmatrix}=\begin{pmatrix}-2k\\k\end{pmatrix}$

On comparing both sides, we get

$k=2$
