Answer:
Step-by-step explanation:
From C-A, it goes from y=1 to y=5, so that 4 units
From A-B, it goes from x = -1 to x = 4, that is 5 units
Now, to find distance from B to C, we need to use the distance formula:
Where the variables are the respective points of B and C,
B (4,5) & C(-1,1)
So x_1 =4, y_1=5, x_2=-1, y_2=1
Plugging into the formula we get:
Summing it all (perimeter is sum of 3 sides):
Distance = 
3rd answer choice is right.
About 9-10 times(when you divide you get a decimal)
Here is the solution..x equals to √3..which is equals to 1.73205
Answer:
the x-axis is the middle horizontal line
the y-axis in the middle vertical line
the origin is (0,0) or where the x and y-axis cross
in the upper left quadrant the x-axis is negative and the y-axis is positive.
in the upper right quadrant the x-axis is positive and so is the y.
in the lower left quadrant both the x and y-axis is negative.
in the lower right quadrant the x-axis is positive and the y-axis is negative.
- Subtraction can be thought of as the inverse operation of addition, OR as addition itself, if you look at it as adding a negative number.
- The number line allows us to interpret subtraction (or addition of a negative) geometrically; we can view it as a movement to the left on the number line with a distance equal to the number being subtracted.
- Lastly, the value of any expression a - b (where a and b are real numbers) is determined by the relative sizes of the numbers. If a > b, then a - b > 0 (a positive result). If b > a, then a - b < 0 (a negative result.
