The answer is C I believe. I wasn't sure what exactly D was saying, but I am pretty sure the answer is C
Answer:
4.123 units
Step-by-step explanation:
Data provided:
Coordinates of point 1 as ( 4 , 2)
and,
Coordinates of point 2 as ( 0 , 1 )
Now,
The distance between the two point whose coordinates are given is calculated using the formula as:
distance = 
on substituting the values, we get
distance = 
or
distance = 
or
distance = 
or
Distance = √17 = 4.123 units
The answer is 221.1 cubic inches
Using the equation V=lwh, and plugging in the numbers, you would get your answer of 221.1 cubic inches
V=lwh
V=16 3/4 x 3 x 4 2/5
V=221.1 cubic inches
Let the number be represented by x
2x=60+ 5x -20*2=60+5*-20
2x-5x=5x-5x+60 -40=60+-100
-3x=60 -40=-40
-3x/-3=60/-3
x=-20
Therefore the number is -20
