Answer:
a) distributive property
b) combining like terms
c) commutative property of addition
Area of large rectangle = 10 * 5 = 50 square units
Area of shaded rectangle = 9 * 3 = 27 square units
the shaded rectangle is 27/50 = 54% of the larger rectangle
100% - 54% = 46% chance of not being in the shaded rectangle
So here is how we are going to prove that (2(tan x - cot x) / (tan^2 x - cot^2 x} = sin (2x). Follow it step by step:
LS = 2(tanx−cotx)
------------------
tan^2−cot^2x
= 2(tanx−cotx)
----------------------
(tanx−cotx)(tanx+cotx)
= 2
-------------------
(tanx+cotx)
= 2
-----------------
Sin2x+cos2x
---------------- sinxcosx
= 2
-------------
1
------------
sinxcosx
= 2sinxcosx
= sin2x
