Answer:

108 - 30x - 116x² - 18x³

Step-by-step explanation:

We have to get the value of - (2x + 12) (9x² + 4x - 9)

Now, using the distributive property of multiplication we get

- (2x + 12) (9x² + 4x - 9)

= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]

= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]

= -[18x³ + 116x² + 30x - 108]

= 108 - 30x - 116x² - 18x³ (Answer)

Help me solve this problem step by step because I’m having a hard time
jarptica [38.1K]

Answer:

x=3, y=10

Step-by-step explanation:

in triangle KLN all the angles are equal making it an equilateral trianlge. GIven one side being 6, we know all the sides are 6 including the side with the expression y-4.

this means

y-4=6

y=10

Using the converse of the base angles theorem(meaning we know the base angles are congruent so the two sides are conguent), we know that

6=x+3

x=3

Which of the following shows the division problem below in synthetic division form? (6x^3+x^2-3)/(x-7)
PSYCHO15rus [73]

Answer:

Option C.

Step-by-step explanation:

If a polynomial P(x) is divided by (x-c), then we write leading coefficients inside the synthetic division line and c outside the synthetic division line.

The given division problem is

\dfrac{6x^3+x^2-3}{x-7}

Here,

x-c=x-7\Rightarrow c=7

The numerator polynomial can be written as

P(x)=6x^3+x^2+0x-3

So, the coefficients of numerator are 6, 1, 0, -3.

The synthetic division form for given division problem is

7      |     6       1      0    -3

Therefore, the correct option is C.

I WILL GIVE BRAINLIEST PLEASE HELP!!!
luda_lava [24]

Answer:

Step-by-step explanation:

interchange x and y

y= 1/(x - 2)

x = 1 / (y - 2)      Multiply both sides by y - 2

x(y - 2) = 1          Remove the brackets

xy - 2x = 1          Add x to both sides

xy = 1 + 2x         Divide by x

y = (1 + 2x)/x

The brackets have been destroyed. The answer is as I've given it.

y = (1/x) + 2
