The answer is about 12.5 (when rounded to the nearest 10th). 

This can be found using the distance formula between each point. One distance is 5, one is \sqrt{2} and one is \sqrt{37}. Added together gives you the answer above.

stiv31 [10]

Answer:

65

Step-by-step explanation:

So we have the expression:

m+2(m-5)

And we want to evaluate it for m=25.

So, substitute 25 for m:

=(25)+2((25)-5)

Subtract:

=25+2(20)

Multiply:

=25+40

Add:

=65

So, our answer is 65.

And we're done!
