Answer:
85
Step-by-step explanation:
Order of operations rules (PEMDAS) govern here.  Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.
Add 2+5 first:    5 + 2*{(7)*5 + 5}
Perform the work shown inside the brackets {  and  }:  5 + 2*{40}
Perform the indicated mult.:  5 + 80
Finally, add:  85
 
        
                    
             
        
        
        
Answer:
Not a right triangle.
Step-by-step explanation:
If this triangle is a right triangle, then the Pythagorean theorem would work on it. According to the Pythagorean theorem,  , so c would always be greater than a or b. In this scenario, the greatest number here is 18, so c = 18. Since a or b don't matter if given both legs, we have the following equation that may or may not be equal:
, so c would always be greater than a or b. In this scenario, the greatest number here is 18, so c = 18. Since a or b don't matter if given both legs, we have the following equation that may or may not be equal:  . We know 8 squared is 64, and 11 squared is 121, and 18 squared is 324. This means that
. We know 8 squared is 64, and 11 squared is 121, and 18 squared is 324. This means that  according to the Pythagorean theorem, and since 64 + 121 = 185, and 185 does not equal 324, the Pythagorean theorem does not work and the triangle is not a right triangle.
 according to the Pythagorean theorem, and since 64 + 121 = 185, and 185 does not equal 324, the Pythagorean theorem does not work and the triangle is not a right triangle.
