Add b to a and multiply 9 by the result without simplifying any part of the expression.
Not simplifying an expression in algebra means not organizing or grouping like terms in the algebraic expression in such a way as to make it more understandable. It is not required in this case. Hence,
To figure this out you need to average the numbers. To average them you add them all up and divide by how many are there. (60+30+20)/3 (90+20)/3 110/3 36
By <span>Pythagorean triple a²+b²=c², c should be longest side 10²+14²=26² 100+196=676 296</span>≠676 so sides do not form Pythagorean triple, it is not a right triangle
