Answer: The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Step-by-step explanation:
The decimal equivalent is -4.666....
In order to find this, we need to start by just taking the whole number for itself.
-4.
Now we have to handle the fraction version. In order to do that, we need to do the division and turn into a decimal.
2/3 = .666...
Now we simply put them together and get our answer.
-4.666...
Answer:
Step-by-step explanation:
Let the other end point be (a,b)
Then the midpoint p(0,-1) is between the two end points (-1,0) and (a,b)
So
(0,-1) = ( (-1+a)/2 , (0+b)/2)
So we have
0 = (-1 +a) /2
0 = -1 + a
a =1
and
-1 = (0+b)/2
-2 = 0+b
b = -2
So the other end point is ( 1, -2)
