In both types of problems you rewrite the problem vertically, line up the decimals, and add zeros or rename where needed..
Answer:
U use the same method when either subtracting or adding decimals
Step-by-step explanation:
hope that will help you
45
73+62=135
180-135=45
180 is the whole area of the triangle
Subtract corresponding x and y components
- u - v = - <- 8, 4> - <2, 7> = <8, - 4> - <2, 7> = <8 - 2, - 4 - 7> = <6, - 11>
u - v = <- 8, 4> - <2, 7> = <- 8 - 2, 4 - 7> = <- 10, - 3>
v - u = <2, 7> - <- 8, 4> = <2 + 8, 7 - 4> = <10, 3>
The solution would be 75911*10^10/462500 or 1.64132 x 10^9
