d =  \sqrt{ ({2 - 4})^{2} +  ({7 - 2})^{2}  }

d =  \sqrt{ ({ - 2})^{2} +  ({5})^{2}  }

d =  \sqrt{4 + 25}

d =  \sqrt{29}

Answer:

15/7

Step-by-step explanation:

To divide fractions, the process is as follows:

1) Flip one of the fractions over (numerator becomes denominator, denominator becomes numerator). In this problem, this step looks like:

5/7 divided by 1/3 ---> 5/7 divided by 3/1

2) Once one fraction is flipped, change the division sign to a multiplication sign. In this problem, this step looks like:

5/7 divided by 3/1 ---> 5/7 * 3/1

3) Multiply the fraction (multiply one fraction's numerator and denominator by the other's) In this problem, this step looks like:

5/7 * 3/1 ---> 15/7.

To check, use the same steps in the problem ? * 1/3 = 5/7. You'll find that 15/7 * 1/3 = 5/7.
