Answer:

Step-by-step explanation:

First, you solve the initial equation 3m+5=23.

3m+5-5=23-5

3m=18

3m/3=18/3

m=6

Second, you input the answer 6 into m in the second equation.

2(6)-3

12-3

Tan 9x - tan 5x/ 1+ tan 9x tan 5x

NeTakaya

Answer:

tan 4x

Step-by-step explanation:

Note the difference identity for tangent ratio is

tan(x - y) = $\frac{tanx-tany}{1+tanxtany}$

Given

$\frac{tan9x-tan5x}{1+tan9xtan5x}$ ← in the form of the right side of the expansion, thus

= tan(9x - 5x)

= tan 4x
