Answer:

○ \displaystyle -6x^2 + 6x + 5

Step-by-step explanation:

Since the divisor is in the form of \displaystyle x - c,use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY <em>REALLY</em> ARE, so do not forget it. Anyway, here is how it is done:

2| −6 18 −7 −10

↓ −12 12 10

________________

−6 6 5 0 \displaystyle \hookrightarrow -6x^2 + 6x + 5

You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [−6x³ + 18x² - 7x - 10]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have <em>no remainder</em>. Finally, your quotient is <em>one degree less</em> than your dividend, so that −6 in your quotient can be a \displaystyle -6x^2,the \displaystyle 6xfollows right behind it, then you end it off with \displaystyle 5,giving you the quotient of \displaystyle -6x^2 + 6x + 5.

I am joyous to assist you at any time.

Find four geometric means between 25 and 800.
SVEN [57.7K]

Actually, you have to find four missed terms of geometrical sequence. Denote

a_1=25,\\ a_6=800

and r - ratio, then

a_2=a_1\cdot r=25r,\\a_3=a_1\cdot r^2=25r^2,\\a_4=a_1\cdot r^3=25r^3,\\a_5=a_1\cdot r^4=25r^4,\\a_6=a_1\cdot r^5=25r^5.

Since a_6=800, you have that 800=25r^5, then

r^5=\dfrac{800}{25} =32,\\r=2.

Now substitude r=2 in each of unknown 4 terms:

a_2=25\cdot 2=50,\\a_3=25\cdot 2^2=100,\\a_4=25\cdot 2^3=200,\\a_5=25\cdot 2^4=400.

Answer: four geometric means between 25 and 800 are 50, 100, 200, 400.

Find the value of x in each triangle. Please help me &lt;33
frozen [14]

Answer:

x = 11

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side

15x + 15 = 180 ( subtract 15 from both sides )

15x = 165 ( divide both sides by 15 )

x = 11
