If point c has coordinates (4, 2) and point d has coordinates (8, 5), then what

5.385164807

or

5.4

Step-by-step explanation:

Use the Distance Formula:

First, do (-4 - -2) exponent 2 + (2 - -3) exponent 2.

So you get: (-2) exponent 2 + (5) exponent 2.

Then, you do -2 times -2, since there is 2 as an exponent. You also do 5 times 5.

So you get: 4 + 25

Next, you add 4 + 25 and get 29.

Finally, you find the square root of 29, which is 5.385164807, or you can round it.

( I hope that is not too confusing. I couldn't do the exponents, so I just wrote it as a word. The whole thing was done with the Distance Formula.)
