Answer:
cos6x.
Step-by-step explanation:
We use the identity
cosAcosB - sinAsinB = cos(A+B)
so cos5xcosx - sin5xsinx = cos(5x + x)
= cos6x.
-5g - 3/h-3 + 7g +9/h-3 = -5g + 7g -3/h-3 + 9/h-3 = 2g + (9 - 3)/(h-3) =
= 2g + 6/(h-3) if we want it as one fraction it would be:
2g + 6/(h-3) = [2g(h-3) + 6]/(h-3) =
7x + 4x - 11 = 22
Add 11 to both sides.
7x + 4x = 22 + 11
Simplify.
11x = 33
Divide both sides by 11.
x = 3

All you have to do is subtract.
1200-10
so
1190
bc 1190 PLUS 10 is 1200
