Answer:
-1/2
Step-by-step explanation:
We can find the slope if we are given two points
m = (y2-y1)/(x2-x1)
= (4-8)/(4 - -4)
= (4-8)/ (4+4)
= -4/8
= -1/2
Answer:
-28
Step-by-step explanation:
-16 +(-12)
= -16 - 12
adding both of them,
= - 28
Answer: GR = 27
Step-by-step explanation:
Given: R is the midpoint of FG.
i.e. R bisects FG into two equal parts as FR and GR. [Midpoint divides a line into two equal parts.]
or we can write FR = GR
Since it is given that FR = 27
Then from (i) , GR = FR = 27
i.e. GR = 27
Hence, GR = 27 , which is the required solution.
Answer:
The length of fencing will be 
Step-by-step explanation:
Step 1
Find the dimensions of the rectangle
we know that
The area of a rectangle is equal to

In this problem we have

so
