Hey there!
Distance formula:
d =
Plug in variables:
d = 
Simplify.
d = 
d =
The distance between the two points is
units.
Hope this helps!
Multiply the second fraction by three.
4/9 + 3/9 = 7/9
Answer: Choice C)
We start at 0 and move 1.4 units to the right. Then we move another 2.3 units to the right to land on 3.7
Notice how 1.4 - (-2.3) = 1.4 + 2.3 = 3.7
1( n * 2)
2(n+2*x)
i hope this helps the question wasn't very specific
