Find the length of the red line segment in the coordinate plane.
Which of the following statements are true:
(1 point)
Responses
a. The length is 40−−√
units; find the sum of the vertical and horizontal distances squared and then take the square root.
b. The length is 40 units; find the sum of the x and y coordinates and square root the answer.
c. The length is 130; find the difference between the x and y coordinates and square it.
d. The length is 260−−−√
; find the difference of the x coordinates and the difference of the y coordinates and subtract those differences.
a. The length is 40−−√
units; find the sum of the vertical and horizontal distances squared and then take the square root. - This statement is true.
b. The length is 40 units; find the sum of the x and y coordinates and square root the answer. - This statement is false.
c. The length is 130; find the difference between the x and y coordinates and square it. - This statement is false.
d. The length is 260−−−√
; find the difference of the x coordinates and the difference of the y coordinates and subtract those differences. - This statement is false.
so whats the answer
The answer is:
a. The length is 40−−√ units; find the sum of the vertical and horizontal distances squared and then take the square root. - This statement is true. The length of the red line segment can be found by using the distance formula in the coordinate plane.
