20x = 1800
x = 90
The museum had 90 paintings in April.
Hope this helps!! :)

Hope this helps
I’m a bit confused confused, but the answer may be -2x^3 + 2x^2 - 2x +2
Work:
To solve this, take the equation for q and the equation for r, and multiply them together.
Use the distributive property to multiply them.
I’m not sure if this is right or not, so pls don’t get mad if it isn’t.
Thank you! :)
Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx
