Answer:
10
Step-by-step explanation:
Let the width length be x.
Width length = x
Length = 2x + 4
Perimeter = width + length + width + length
= x + 2x + 4 + x + 2x + 4
= 6x + 8
6x + 8 = 28
6x = 28 - 8
= 20
x = 20 ÷ 6
x = 3
Length (2x + 4) = 2(3) + 4
= 6 + 4
= 10
Answer:
<u>Slope</u>- -5/2 <u>Y Int.</u>- 4
Step-by-step explanation:
You would first need rto put the equation in slope intercept form by subtracting -5x and adding 8 to both sides the you will divide two from each #. Then your equation will be in slope intercpt form which allows you identyify 4 as the y intercpt and -5/2x as the slope.
2y+5x-8=0
-5x +8 -5x + 8 = 2y=-5x+8
2y/2=-5x/2+8/2
y=-5/2x+4
