So, first you would distribute 2 and 1/4 which is 1/2z then do 2 times 8 which is 16 and have it as 1/2z-16 then take 1/4z and add it to 1/2 since your adding the two expressions. So whatever 1/4z plus 1/2z is then you subtract is to 16 minus 6, because 6 is in your other expression. It's kinda hard to explain but the answer is C haha Hope this helped!

Answer:
This is a right triangle
Step-by-step explanation:
We will use the Pythagorean theorem
a^2 + b^2 = c^2
If this is true it is a right triangle
5^2 + 12^2 = 13^2
25+144 = 169
169 =169
This is true so this is a right triangle
