The First is sec^2(x). Second is 2sec^2tanx. From that you get 2[2sec^2xtan^x+sec^4x]
The answer is 6 pi because you have to divide 18 by 3. That gives you 6.
Answer:
a
Step-by-step explanation:
you would add three to both sides because you are subtracting on the left side, so you would use inverse operations
First distribute the -3 and the - sign
6x + 24 + 5x - 6
Combine like terms
11x + 18
question 9
a) 2 x 3 = 6m^2
b) diameter = 2m and radius = 1m
c) πr^2 is the equation, so 3.14 x 1^2 = 3.14m^2
and the semi circle is half of that, 1.57m^2
d) 6 + 1.57 = 7.57m^7
question 10
30 x 70 = 2,100m^2
πr^2 so 3.14 x 15^2 = 706.5m^2
2,100 + 706.5 = 2,806.5m^2
i hope this is correct :D
