Answer:
x-3
Step-by-step explanation:
f(x) = 3x-2
g(x) = 2x + 1
(f-g)(x) = 3x-2 - ( 2x+1)
Distribute the minus sign
=3x-2 -2x-1
Combine like terms
= 3x-2x -2-1
=x-3

Answer:
The area of the rectangular playroom is 260 feet² .
Step-by-step explanation:
Given:
The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.
Now, to find its area we need the length .
So, putting the formula of perimeter we get it's length:
Let the length be l .
Perimeter = 2( length + width)


subtracting both sides from 20:


Dividing both sides by 2:


Length is 26 feet.
And, to get the area we put the formula of finding the area:



Therefore, the area of the rectangular playroom is 260 feet² .
