When 12x² + kx + 3 and 3x³ + (3k + 2)x² + 28x +17

Naily [24]

Answer:

$\boxed{\sf \ \ \ k=5 \ \ \ }$

Step-by-step explanation:

Hello,

We know that for a real, the polynomial P(x) divided by (x-a) the remainder is P(a)

and as

$3x+2=03x=-2x=\dfrac{-2}{3}$

so we need

$12(\dfrac{-2}{3})^2+k(\dfrac{-2}{3})+3=3(\dfrac{-2}{3})^3+(3k+2)(\dfrac{-2}{3})^2+28\dfrac{-2}{3}+17\\ \ multiply \ by \ 9\\ 12*4-6k+27=-8+4(3k+2)-28*2*3+17*9\\ -6k+48+27=-8+12k+8-168+153\\ -6k+75=12k-15\\ 18k=75+15=90\\ k = \dfrac{90}{18}=\dfrac{15}{3}$

hope this helps

Does 4/7 lies between the numbers -3/5 and 3/4

Nesterboy [21]

one way to do this is to convert each fraction to same denominator ( the LCD)

Well we can eliminate -3/5 because its negative so 4/7 is definitely > -3/5.

4/7 = 16/28 and 3/4 = 21/28

so 4/7 < 3/4

Therfore 4/7 does lie between the 2 fractions

Q(3x)=12x+2 then what is Q(x-2)

Mandarinka [93]

Answer:

it's ax+b form answer is Q(x-2)=4x-6

Step-by-step explanation:

ax+b=Q(x),Q(x-2)=a(x-2)+2

Q(3x)=a(3x)+b=12x+2, 3a=12 =>a=4,b=2

the original q of x is 4x+2

Q of x-2 =4(x-2)+2=4x-8+2=4x-6
