Another math problem; algebra help!?
Okay so I dont know how to distribute this problem.
1. 3 - (2 + 3x)
One of these are the answers.
a. 1 - 3x
b. 1 + 3x
c. 5 + 3x
i think i did it right but i just want to make sure i got the correct answer.
Also The property demonstrated in the equation 2(4 - n) = 2(4) - 2(n) is DISTRIBUTIVE right?
If w represents the width of a rectangle 12 inches long with a perimeter of 60 inches, the best algebraic representation of the rectangle's perimeter is
a. 60 + 24w
b. 60 = 24 + 2w
c. 60 = 12w
A garden's length is 3 times its width. It takes 18 meters of fence to enclose the garden. Which equation best represents the perimeter of the garden in one variable?
a. 18 = 6w
b. 18 = 2l + 2w
c. 18 = 2(3w) + 2w
Please help me. I have the answers I just dont know if i did it right.
I want to make sure I got the correct answer since no one in my family knows how to do these

1. In the first problem you are distributing the negative sign to (2 + 3x)
first -(2) = -2
-(3x) = -3x
so now we have 3 -( 2+3x ) = 3+ ( -2-3x)
3 + (-2 - 3x)=
3 - 2 -3x=
Yes your second question is distributive
woops sorry i thought you said area
60 = 24w + 2l

The fisrt one should be 1-x, the 3's cancel each other.
2) it should be b but you mising a leter, 60=24w+2l.
