Solve for c 6/15=2/c
saul85 [17]
\frac{6}{15} = \frac{2}{c}   Multiply both sides by 15
6 = \frac{30}{c}   Multiply both sides by c
6c = 30   Divide both sides by 6
c = 5

Using long division to find the quotient, what changes do you first
lora16 [44]

Answer:

\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4

Step-by-step explanation:

Given

Dividend = 125x^3 - 8

Divisor = 5x - 2

Required

Determine the quotient

See attachment for complete process.

First, divide 125x^3 by 5x

\frac{125x^3}{5x} =25x^2

Write 25x^2 at the top

Multiply 5x - 2 by 25x^2

= 125x^3 - 50x^2

Subtract from 125x^3 - 8

i.e.

125x^3 - 8 - (125x^3 - 50x^2) = 50x^2 - 8

Step 2:

Divide 50x^2 by 5x

\frac{50x^2}{5x} = 10x

Write 10x at the top

Multiply 5x - 2 by 10x

= 50x^2 - 20x

Subtract from 50x^2 - 8

i.e.

50x^2 - 8 - (50x^2 - 20x) = 20x - 8

Step 3:

Divide 20x by 5x

\frac{20x}{5x} = 4

Write 4 at the top

Multiply 5x - 2 by 4

= 20x - 8

Subtract from 20x - 8

i.e.

20x - 8 - (20x - 8) = 0

Hence:

\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4

Answer: Bottom-Right corner
The points are (-5,6) (-5,-6) (4,-6)

-----------------------------------------

Explanation:

What you do is go through each of the answer choices, plot the points, and see which give you a right triangle. A right triangle has one 90 degree angle. 

The upper-left choice leads to an obtuse triangle, so we can cross that off the list. It turns out that the other choices lead to right triangles.

The upper-right choice has a hypotenuse of roughly 11.18, so that's also eliminated

The bottom-left choice has a hypotenuse of 10.82, which means we cross that off the list

The bottom-right choice has a hypotenuse of 15, so we found the answer

Note: you use the distance formula to find the length of the hypotenuse. The distance formula is
d = sqrt((x1-x2)^2+(y1-y2)^2)
