Answer:
4
Step-by-step explanation:
(a+2)(a-1) - (a+1)(a-2)
put a=2
(2+2)(2-1) - (2+1)(2-2)
4*1 -3*0

Answer:
17
Step-by-step explanation:
According to the Pythagorean theorem, 
, where a and b are the two legs of a right triangle, and c is the hypotenuse. In this scenario, the two legs are 8 and 15, and we are asked to find the hypotenuse. Plugging the two values in, we have 
, where 64 is 8 squared and 225 is 15 squared. Adding, we have the two values as 289. If you don't know your squares, I suggest you take a look at a list or even memorize your squares until 30, but 289 is actually 17 squared. If 
, then c = 
, which is 17.
