Step-by-step explanation:
Dont listen to the person above, they put the same link everhwher
25 = 5*5 and 9 = 3*3, which we can exploit to write
so that this expression is actually a difference of squares. We can factorize this to get
and given that 
, we divide both sides by this to get
Answer:
68
Step-by-step explanation:
x = 32
To find the media, you take the middle number. If there is no discrete middle number, take the sum of the two closest to the middle and divide by 2.
(24 + x)/2 = 28
Multiply by 2 on both sides to get:
24 + x = 56
Subtract 24 from both sides to isolate the variable:
x = 56 - 24
x = 32
