A=wl \Rightarrow 
l=\frac{A}{w}
l - length, A - area, w - width

A=x^3-2x-4 \\
w=x-2 \\ \\
l=\frac{x^3-2x-4}{x-2}=\frac{x^3-2x^2+2x^2-4x+2x-4}{x-2}=\frac{x^2(x-2)+2x(x-2)+2(x-2)}{x-2}=\\
=\frac{(x^2+2x+2)(x-2)}{x-2}=x^2+2x+2

The answer is D.

find the height and of a parallelogram if its base is 35 centimeters and its area is 700 square centimeters
OLEGan [10]
Hello!

We know what the base and area of the parallelogram are, but the height is still unknown. We also know that the formula for the area is: 

A = bh

Meaning we multiply the base by the height to find the area. The opposite of multiplication is division, so we must divide the area by the base to find the height. (We work in the opposite way).

B = a / h 

B = 700 cm² / 35 cm

B = 20 

We can double check by multiplying 20 by 35, and the product should result in 700. 

20 * 35 = 700

Therefore, the height of the parallelogram is 20 centimetres.

Kevin designs a sprinkler system for his yard. One rotation of the the sprinkler waters a circle with an area of 255pie square f
pantera1 [17]
The area of a circle can be found using:
pi x r^2 (where r is the radius)

If the area of the circle is 255pi, then:
pi x r^2 = 255pi

Now we need to make r the subject:

r^2 = 255 (cancel the pi on both sides)

r = square root of 255

r = 15.96871942

Answer: 15.96871942 feet
Hope the answer helps :)

What is the area of rectangle when both circles have a radius of 2
tia_tia [17]
Figure out the length of the rectangle by using the diameter of the 2 circles added together then work out the width by using the diameter of one circle (since the vertical diameter will be the same length as the width if that makes sense)
