Step-by-step explanation:
The way that I would do it, would be to use the point distance formula to find the length of each side.
Distance formula: 
After you use this formula to find the length of all sides of the polygon, you would need to use the appropriate area formula to find the area of the polygon.
Area of Triangle: A= 1/2 base times height
Area of Rectangle: A= length times width
Area of Square: A= s^2 where s is the length of the side
Area of Parallelogram: A= base times height
Area of Trapezoid: A= 1/2 times height (base 1 + base 2) where base 1 and base 2 are the parallel sides
Area of Kite or Rhombus: A= 1/2 (diagonal 1 times diagonal 2)
Area of Regular Polygons: A= 1/2 (apothem times perimeter)
Given Situation : If 5 days ago is Friday, then what day of the week will be the day after tomorrow.
Answer:
If 5 days ago is Friday.
DAY1 is
- Saturday
DAY 2 is
- Sunday
DAY 3 is
-Monday
DAY 4 is
- Tuesday
DAY 5 is today
- And today is Wednesday
DAY 6
- Tomorrow is Thurdays
DAY 7
- Which is the day after tomorrow is Friday
Thus, the day that we are looking is Also Friday.
My suggestion is to look on google, there are plenty of answers and I think it will explain better than me.
It's going to be 2.4 * 10 to the power of 6.
Hope this helped =)
You will need to work left to right.
p - 10p + -5p +14p - -9p - 2 = -20
-9p + -5p +14p - -9p - 2 = -20
-14p +14p - -9p - 2 = -20
0p- -9p - 2 = -20
9p - 2 = -20
Then you will want to eliminate 2 by adding it to both sides
9p = -18
Then divide by 9 to isolate P
p=-2
