The first one is 10k²-7k-6
The second answer is 8k²-26k+18
35 degrees.
Assuming 145 is the exterior angle, the interior is 35. 180-145=35
Add 110 to 35 and get 145 degrees. Which leads the remaining angle 35 degrees
Use the permutation formula
nPr = (n!)/((n-r)!)
20P15 = (20!)/((20-15)!)
20P15 = (20!)/(5!)
The final answer is choice A
Solution:
we have been asked to find the equation of the line that passes through (7, 4) and (4, -2).
First we will find the slope of the line using the formula

Plugin the given values we get

Now using the point slope form of a straight line

Plugin the values

Hence the correct option is a.
