Answer:
The answer for this problem is x^2+x-12
Answer:
Step-by-step explanation:
let the numbers be 7x,y,y,y.
7x+3y=36
3y=36-7x

numbers are 7×3,5,5,5
or 21,5,5,5
21×5×5×5=2625

Answer:
1,078
Step-by-step explanation:
I got that answer by multiplying 22 and 49. We know that product means to use the multiplication operation so our problem would look like this:
22 * 49 = 1,078
Cos2x = (cosx)^2 - (sinx)^2;
sin2x = 2sinxcosx;
Then, (2cos2x)/(sin2x) =2[ (cosx)^2 - (sinx)^2 ] / (2sinxcosx) = [ (cosx)^2 - (sinx)^2 ] / (sinxcosx) = (cosx)^2 / (sinxcosx) - (sinx)^2 / (sinxcosx) = cosx/sinx - sinx/cosx = cotx - tanx;
