Answer:
If you are below the age of 18 then you are not regarded as a grown up person.
1a= (2x+5)+3x+15
1b= (2(4)+5)+3(4)+15=40
2a= (3x+5)•(4x-3)
2b= (3(2)+5)•(4(2)-3)=55
2c= 2(x) or 2(2)
How I got 2c is the perimeter of the rectangle LMNP subtract from (2(2)+9)+(2(2)+9)=26 which in return means you subtract 30 from 26 and get 4 which is 2(2) or 2x
Both are functions. Try not to get tripped up on notation of functions. They are they same, just written differently.
f(x) = 3x-10 is the same as 0=3x-10
2x+7y=28 is the same as 2x+7y-28=0
Just one will give you a line and the other will give you a circle. If you are ever unsure, plug them into a graphing calculator and see what you get back.
