Answer:
2x² + 
x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus

= 2x² + x - 5
16, if there’s no space left and each book is 1 inch wide any number times one is itself, 16(books)x1(inches)=16
If you would like to know a number you can square and the answer is bigger than 400 but smaller than 500, you can calculate this using the following step:
20^2 = 400 < 21^2 = 441 < 22^2 = 484 < 500
There are two correct results: 21 and 22.
