I think you have to do 120-60% and the answer is 48 dollars.
If the question is 40 - 
, then you would do 16 ÷ 4 = 4, and then 40 - 4 = 36.
If the question is 
, then you divide both 40 and 16 by 4, to get 10 - 4 = 6.
I hope this helps!
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]-by-
