7 - 2 (3 - 8x)
7 - 6 + 16x
1 + 16x
Nothing further can be simplified.

Answer:
see explanation
Step-by-step explanation:
Using the cofunction identities
tan(90 - A) = cotA and cscA = sec(90- A)
Consider the left side
tanA + tan(90 - A)
= tanA + cotA
= 
+ 
= 
= 
= 
× 
= secA × cscA
= secA. sec(90 - A) = right side ⇒ verified
If there's only 1 table, then you need 5 roses total (5*1 = 5)
If there are 2 tables, then you need 10 roses total (5*2 = 10)
If there are 3 tables, then you need 15 roses total (5*3 = 15)
If there are 4 tables, then you need 20 roses total (5*4 = 20)
At this point, you probably see the pattern: you multiply 5 by the number of tables to get the total number of roses. So it would look like this equation
(number of roses) = 5*(number of tables)
r = 5*x
where r is standing in for "number of roses" as shorthand; also, x is standing in for "number of tables".
------------------------------------------------------------------------
Final Answer: r = 5x (lower right corner choice)
Note that 5*x is the same as 5x (both of which mean "5 times x)
