Distance between two points P(x1,y1), Q(x2,y2):
D=sqrt((x2-x1)^2+(y2-y1)^2)
Polygons are generally named in order along the perimeter, so that for a rectangle ABCD, AC or BD are diagonals.
Here, we need the distance between points A(4,3) and C(-4,-2)
Applying the above formula for distance between two points,
D=sqrt((4-(-4))^2+(3-(-2))^2)=sqrt(8^2+5^2)=sqrt(64+25)=sqrt(89)
Answer:
32.2 is your answer for c
Step-by-step explanation:
Note the equation:
c - 23.7 = 8.5
Note the equal sign. What you do to one side, you do to the other. Isolate the c. add 23.7 to both sides
c - 23.7 (+23.7) = 8.5 (+23.7)
c = 8.5 + 23.7
Simplify.
c = 32.2
32.2 is your answer for c

Step-by-step explanation:
Here important information is missing. That is total number of divide.
However, it is given that riley made groups of 12 with 1left over from total number of divide. So, total number of divides on the drawing must be a multiple of 12 +1. It can be any number like 12n+1, where n is an integer. Then we ca find total number of group.
