It is the simplest expression which is a multiple of both of the original denominators. Then, the numerators only are added, and the result is divided by the lowest common denominator. Example. Express as a single fraction.
Slope = rise/run
rise = 7 - 3 = 4
run = -2 - 2 = -4
slope = 4/-4 = -1
Answer is B
RE is a line, so angles RPL and EPL form a linear pair and are supplementary.
Supplementary angles are two angles whose measures add up to 180 degrees.
3z + 2z = 180
5z = 180
z = 36
m<RPL = 3z = 3 * 36 = 108
m<EPL = 2z = 2 * 36 = 72
Answer: D. 108 and 72
The area of a circle is given by:

Where r is the circle's radius. In this case we have a diameter of 8cm so the radius 4cm. Using pi=3.14 we have that the area of the circle is:

So the area is 50.24 cm^2.
Angle 1 is a right angle, so therefore:
3y-6 = 90
3y = 96
Y = 32
I hope this Helps!
