k: the number of Kurds

t: the number of Turks

k=k

t=4k

k+t=66,000,000

k+4k=66,000,000

5k=66,000,000

k=13,200,000

t=52,800,000

1) $x^2=x\cdot x$ , and $x(x+3)=x^2+3x$ . Subtracting this from the numerator gives a remainder of

$(x^2-13x-48)-(x^2+3x)=-16x-48$

$-16x=-16\cdot x$ , and $-16(x+3)=-16x-48$ . Subtracting this from the previous remainder gives a new remainder of

$(-16x-48)-(-16x-48)=0$

This means that

$\dfrac{x^2-13x-48}{x+3}=x-16$

2) $3x^3=3x^2\cdot x$ , and $3x^2(x+2)=3x^3+6x^2$ . Subtracting this from the numerator gives a remainder of

$(3x^3-x^2-7x+6)-(3x^3+6x^2)=-7x^2-7x+6$

$-7x^2=-7x\cdot x$ , and $-7x(x+2)=-7x^2-14x$ . Subtracting this from the previous remainder gives a new remainder of

$(-7x^2-7x+6)-(-7x^2-14x)=7x+6$

$7x=7\cdot x$ , and $7(x+2)=7x+14$ . Subtracting this from the previous remainder gives a new remainder of

$(7x+6)-(7x+14)=-8$

This means that

$\dfrac{3x^3-x^2-7x+6}{x+2}=3x^2-7x+7-\dfrac8{x+2}$

3) $x+2$ will be a factor of $x^3+3x^2-10x-24$ if dividing the latter by $x+2$ leaves a remainder of 0.

$x^3=x^2\cdot x$ , and $x^2(x+2)=x^3+2x^2$ . Subtracting this from the numerator gives a remainder of

$(x^3+3x^2-10x-24)-(x^3+2x^2)=x^2-10x-24$

$x^2=x\cdot x$ , and $x(x+2)=x^2+2x$ . Subtracting this from the previous remainder gives a new remainder of

$(x^2-10x-24)-(x^2+2x)=-12x-24$

$-12x=-12\cdot x$ , and $-12(x+2)=-12x-24$ . Subtracting this from the previous remainder gives a new remainder of

$(-12x-24)-(-12x-24)=0$

and since the remainder is 0, $x+2$ is indeed a factor of $x^3+3x^2-10x-24$ .

Points A, B, and C are collinear. Point B is between A and C. BC=8x+709. AB=487+5x. AC=91. Find BC.

Zolol [24]

Answer:

Step-by-step explanation:

Point B is between A and C and the points A, B, and C are collinear so:

AB + BC = AC

487 + 5x + 8x + 709 = 91

13x + 1196 = 91

- 1196 - 1196

13x = - 1105

÷13 ÷13

x = - 85

BC = 8x + 709 = 8(-85) + 709 = - 680 + 709 = 29

Use gcf and distributive property to find the sum of 18 and 24

Black_prince [1.1K]

Step-by-step explanation:

Since the GCF of 18 and 24 is 6, we can distribute 6 into each number.

$6(3) + 6(4) = 18 + 24 \: (when \: multiplied)$

Also represents;

$6(3 + 4) = 18 + 24$

And;

$6(7) = 18 + 24$

When solved;

$42 = 18 + 24$

Rita has 3/4 gallon of lemonade. She pours 1/8 gallon of lemonade into each glass. How many glasses can she pour?

bearhunter [10]

Answer: 6 glasses.

Step-by-step explanation:

You have to multiply the denominator of 3/4 by two and the numerator by 2 to get 6/8. If you're pouring 1/8 into each glass, then you should be able to have 6.
