I would use the pythagorean theorem to find the lengths of each side. a² + b² = c².
Side AB is one we're looking for. If you make other right triangle with that same side you can see that one length is 4 and the other is 3. So, 4² + 3² = c² → 25 = c² → 5 = c. Side AB is length 5.
Side AC is another. Do the same with that side and you get that one length is 4 and the other is 3. (This is the same one as above) so side AC is length 5.
Side BC is the last one. One of the lengths is 1 and the other is 1 → 1² + 1² = c² → 2 = c² → 1.414213562 = c so side BC is approximately length 1.41.
Add each length up and you get a perimeter of roughly 11.4
-12 is the answer for the slope!
expression is equivalent to 
We apply exponential property
Multiply the outside exponent 1/2 with exponents inside the parenthesis
1/4 times 1/2 is 1/8
16 times 1/2 is 8
so expression becomes
So the answer is
13/12 Is simplified to its simplest form but you can make it an improper fraction which would be 1 1/12. Hope this helps.
25% = 25/100
25% of <u>2</u><u>8</u> is 7
