Answer:
(the relation you wrote is not correct, there may be something missing, so I will simplify the initial expression)
Here we have the equation:

We can rewrite this as:

Now we can add and subtract cos^2(x)*sin^2(x) to get:

We can complete squares to get:

and we know that:
cos^2(x) + sin^2(x) = 1
then:

This is the closest expression to what you wrote.
We also know that:
sin(x)*cos(x) = (1/2)*sin(2*x)
If we replace that, we get:

Then the simplification is:

Answer:
is there a question or picture?
Maybe 63 if you Estimate it
Answer:
21120
Step-by-step explanation:Because you take 5280 and multiply it by 4
If x- 7 = 14 then X = 21. so 21-2= 19. :)
