Answer:
Step-by-step explanation:
We have a certain expression and are asked to find its equivalent with the answers provided :
Remove the parenthesis around 3m^5 :
Do the exponent rule for outside and inside exponent parenthesis :
Apply addition exponent rule :
Add :
Apply the addition rule for -12 + 5 :
Apply negative exponent rule for m^-7 :
Multiply the fractions :
1) It's best to draw out a picture of a rectangle and label each corner with the coordinates given: Let's say (-5, 2) is point A, (-5, -2 1/3) is point B, (2 1/2, 2) is point C, and (2 1/2, -2 1/3) is point D.
2) That being said, line AB is one side of the rectangle, BC is another, CD is another, and lastly, AD is the fourth side.
3) We can use the distance formula and plug in the coordinates of each line to find how long every side is. Then you just need to solve it.
For example: if I want to find how long side AB is, I would use the point A (-5, 2) and B (2 1/2, 2) and plug them into the distance formula, where (-5, 2) is (x1, x2) and (2 1/2, 2) is (x2, y2) and solve that.
4) Repeat this process with side BC, CD, and AD, and add the results together. This will be your final answer; the perimeter of the rectangle.
