Answer:

The division will be represented as:

$\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}$

Step-by-step explanation:

1) Let's find a number with a variable that multiplied by 6x gives as 18x². It will be 3x, because (6x+5)3x=18x²+15x.

Now, let's subtstract:

$(18x^{2}-3x+4)-(18x^{2}+15x)=-18x+4$

2) Let's find a number with a variable that multiplied by 6x gives as -18x. It will be -3, because (6x+5)(-3)=-18x-15.

Now, let's subtstract:

$(-18x+4)-(-18x-15)=19$

Therefore, the division will be represented as:

$\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}$

I hope it helps you!

I need the answer plz

egoroff_w [7]

Answer:

I can't solve and show it but only tell a method to do it!

So find the zero of the given factor:

i.e.

$(x + 1) \\ x = - 1$

Now put its value (-1) in the polynomial

${x}^{3} - 13 {x}^{2} + 32x - 20$

Now if the answer comes zero it is a factor.

You'll get your answer!

What is the range of g(x) = - 2x + 3, if the domain is {-2, - 1,0, 1, 2}?

pshichka [43]

Answer:

{ - 1, 1, 7, 23 }

Step-by-step explanation:

To find the range substitute the values from the domain into g(x)

g(-2) = -2(- 2) + 3 = 4 + 3 = 7

g(- 10) = - 2(- 10) + 3 = 20 + 3 = 23

g(1) = - 2(1) + 3 = - 2 + 3 = 1

g(2) = - 2(2) + 3 = - 4 + 3 = - 1

Range is { - 1, 1, 7, 23 }

If a=i-2j and b= 2i - xj are parallel, then x is.....<br>a) 4 3 2 ) 2 d 4.

cupoosta [38]

Answer:

x = 4

Step-by-step explanation:

a = i-2j

b = 2i-xj

1 = k•2

-2 = k•(-x)

=> 1/2 = k

=> (-2)/(-x) = k

=> 1/2 = (-2)/(-x) => 1/2 = 2/x => x = 4

Anyone mind helping?

elena-s [515]

Answer:

15 x^8 y^3

Step-by-step explanation:

The area of a rectangle is given by

A = l*w where l is the length and w is the width

A = ( 5x^6 y^2) *( 3x^2 y)

= 15 x^(6+2) y^(2+1)

= 15 x^8 y^3
