Let the width be w. Therefore we can right the length as w+2=l. We know the formula for perimeter is 2w + 2l = P. We can fill this formula in to help solve this problem with the pieces we have.
2w+2(w+2)=24
2w+2w+4=24
4w=20
w=5
So, we now know the width of the room. Next, lets plug that into the perimeter equation again and solve for the length now.
2(5) + 2l = 24
10 + 2l = 24
2l = 14
l=7
So the width is 5m and the length is 7m.
Presenting the table vertically makes it easier to read:
X F(x)
-1 -5
0 -1
1 3
I see that if x increases by 1 from 0 to 1, y increases by 4 from -1 to 3. Thus, the slope of the line represented by the table is:
4
m = -------------- = 4/1 = 4
1
So, our two lines have the same slope: 4.
g(x) = 4x + 3; f(x) = 4x - 1
but they have different y-intercepts. Thus, the 2 lines are parallel and never cross one another.

Answer:
Easy peasy :D
You originally have 20 peanuts + 10 = 30 peanuts
Your friend gives you 3 times how much you have now
3 x 30 = 90 peanuts! :)
so 90 peanuts, plus your now 30 B)
Hope this helped!
Answer:
see below
Step-by-step explanation:
1.)
(0, 4)
(1, 7)
y = 3x + b
(4) = 3(0) + b
b = 4
y = 3x + 4
Rate of change: 3 initial value: 4
2.)
(0, -5)
(1, -3)
y = 2x + b
(-5) = 2(0) + b
b = -5
Rate of change: 2 initial value: -5
