The number of large boxes is 4 and the number of small boxes is 14.
<u><em>Explanation</em></u>
Suppose, the number of large boxes is
and the number of small boxes is 
As, the total number of boxes is 18, so the first equation is....

The large boxes hold 35 books, and the small ones hold 20 books and the total number of books is 420. So the second equation will be .....

Now solving equation (1) for
itself , we will get....

We will plug this
into equation (2). So.....

Now plugging this
into the equation
.......

Thus, the number of large boxes is 4 and the number of small boxes is 14.
Hello!
As you can see this figure is a rectangular prism. Two sides are squares. When the figure is cut facing the squares, the resulting shape will be a square.
I hope this helps!
Hello,
The inverse of the function is f^-1(X)=-3-x
How?
f (x)=-x-3
replace f(X) with y
y=-x-3
interchange the variables
x=-y-3
solve for y and replace f^-1 (X)
Hope this helps
Answer:
the answer is A or F (both are the same answer which is 40)
