Answer:
Below.
Step-by-step explanation:
- tan 2x = -2tanx / (1 - tan^2x)
Using the identity tan^2x = sec^2x - 1 and substituting for tan^2x:
- tan 2x = -2 tanx / (1 - (sec^2x - 1))
= 2 tanx / ( - 1(sec^2x + 2))
= 2 tan x / (sec^2 x - 2)
40% of 120 is 48
1/4 of 200 is 50
1/4 of 200 is bigger.

Answer:

Step-by-step explanation:
We are asked to find the product of
and
.
Upon writing our expression as a product we will get,

Let us convert our given mixed fractions to improper fractions.
Upon cancelling out 3 from our given expression we will get,
Upon dividing -7 by 2 we will get,

Therefore, our expression simplifies to -3.5.
