Answer:
1/5
Step-by-step explanation:
-5 - (-7) = 2
5 - (-5) = 10
2/10 ÷2
slope = 1/5
The answer is r=16 you have to square everything
Answer:
the answer is 28d + 42
Step-by-step explanation:
multiply what's on the brackets them add
C+s=48
2c+4s=134 ⇒ c+2s=67
subtracting the equations, we get, s=67-48=19,
so, c=48-19=29
D(7, 3), E(8, 1), and F(4, -1)
We calculate the squared distances between the points:



Since
we have a right triangle with hypotenuse DF.
