You would need to use the distance formula.
Distance = Sqrt((x2-x1)^2+(y2-y1)^2)
Plug in your numbers
Distance = Sqrt((12+4)^2+(12-18)^2)
Distance = 17.09
Answer: 0.6
Step-by-step explanation: First, you want so seperate the equations in parenthesis to make solving the equation easier.
(-2/3x-9/8x )-(4/5x)-(1)
So (-2/3x-9/8x) equals -11/24x
And -11/24x-4/5x equals -151/120x
So -151/120x-1 ends up being 0.6.
The answer is c!!!! hope this helps
Move all terms to the side of the answer x = -8/7 Hope this helps! ;D
Answer:
tan 4x
Step-by-step explanation:
Note the difference identity for tangent ratio is
tan(x - y) = 
Given
← in the form of the right side of the expansion, thus
= tan(9x - 5x)
= tan 4x
