Answer:

The distance between the points is d=2\sqrt{5}\ units   or d=4.472\ units  

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

(7,-3)\\(5,1)  

substitute the values

d=\sqrt{(1+3)^{2}+(5-7)^{2}}

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

d=\sqrt{20}\ units

d=2\sqrt{5}\ units  ----> exact answer

d=4.472\ units  -----> approximation to three decimal places

IgorC [24]
First you have to make them both common denominators
the common denominator is 6 so then half of 6 is 3 so it is 3/6 and then 1/3 converted to a denominator of 6 is 2/6 so the answer is 3/6+2/6= 5/6
