Answer:
A. D=sqrt( (x2-x1)^2+(y2-y1)^2 )
Step-by-step explanation:
The distance between two points is the root of the sum of the squares of the differences in their corresponding coordinates. The equation of choice A is the usual formulation.

<em>Comment on answer choices</em>
Because the square of a number is the same as the square of its opposite, the formula in choice D is also correct.
Answer:
x= 11
A=59
B= 37
C = 84
Step-by-step explanation:
A triangle adds up to 180 °.
So the equation will be a °+ b° + c° = 180°
Next, you combine like terms.

Then inverse operation,

After to get a, b, and c you just need to plug in x.

715 because 275/5= 55 then 55x13 will give you 715
If 2 Lines are crossing together to make 2 pairs of Vertical Angles, the sum of all 4 Angles will always be equal to 360°.
Put each number where Y should be (so 24/3 or 39/3) then simplify. If it is less than or equal to 12 than it satisfies the equation. A. Yes B. No C. Yes and D. Yes
