Answer:
i think correct answer is minus 2 and zero
Hello there!
Your answer is:
Length = 20
Width = 12
Explanation and Work:
-----------------------------------------------------------------------------------------------------
To solve this, we must make a system of equations.
<span>2L + 2W = 64
</span>
<span>L = (2W-4)
Now, we must plug (2W-4) into the first equation for l
2(2W-4) + 2w = 64
2 * 2w = 4w
2 * -4 = -8
4w - 8 + 2w = 64
6w - 8 = 64
Now let's solve this
6w - 8 = 64
+8 +8
6w = 72
Now, divide 72 by 6
72/6 = 12
w = 12
Now, we must plug 12 into the second equation into the w.
L = (2W-4)
L = 2 * 12 - 4
L = 24 - 4
L = 20
So, we know that L = 20 and w = 12
That means
Length = 20
Width = 12
Now, let's check this.
(12 * 2) + (20 * 2) = 64
12 * 2 = 24
24 + (20 * 2) = 64
20 * 2 = 40
24 + 40 = 64
24 + 40 = 64
64 = 64
I hope I helped!

Step-by-step explanation:
<span>we now know that the slope is -2 and since parallel lines have the same slope we know the line we are getting the equation to has a slop of -2. From here there are 2 ways to do this problem we can either use point slope formula or sub in the point and slope into the eqation y=mx+b and solve for b.
<span>Using point slope formula
y-y1=m(x-x1)
where y1=1, x1=3, and m = -2
y-1=-2(x-3)
y=-2x+6+1
y=-2x+7
</span><span>using algebra
y=mx+b
where y=1 m=-2 and x=3
1=-2(3)+b
1=-6+b
7=b
y=-2x+7</span></span>
