Is that the whole question?
5.The answer for 5 is 582 because you do how many times 4 goes into 2 and that 0.so you bring the 3 down and it goes into 23 5 times.5 times 4 is 20.23-20=3.bring down the 2 and 4 goes into 32 8 times.8 times 4=32.subtract that and get 0.bring down the 8 and 4 goes into 8 2 times.
The answer to 7. is 197 because you do 985 divided by 5.
8. For the Lees you would do 632 divided by 4=$158.For the Santos you would do 328 divided by 2=$164.
The Lees rental cost was lower because when you divide them you get $158 for the Lees and $164 for the Santos.
Step-by-step explanation:
3 tan 2x - 4 tan 3x = tan² 3x * tan 2x
3 (tan 2x - tan 3x) = tan 3x + tan² 3x * tan 2x
= tan 3x (1 + tan 3x * tan 2x)
3 (tan 2x - tan 3x)/(1 + tan 3x * tan 2x) = tan 3x
3 * (- tan x) = tan 3x
-3tanx = (3 tan x - tan³ x) / (1 - 3 tan² x)
3 - tan² x = - 3 + 9 tan² x
tan x = + √3 /√5 or - √3/√5
