Answer:

They are neither.

Step-by-step explanation:

Graph both equations using either a graphing calculator or doing it by hand.

Observe the behaviors of the lines; Perpendicular lines bisect each other at a perfect 90 degree angle, while parallel lines never touch each other and are symmetrical.

Answer:

Neither

Step-by-step explanation:

We need to transform one of the equations into its slope-intercept form:

y + 2/5x = 8

Subtract 2/5x from both sides:

y = -2/5x + 8

y = -5/2x - 7

Graphing both lines, they do intersect at point (-7.14, 10.86), but they are not parallel, nor are they perpendicular from each other. By definition, perpendicular lines must appear to be perpendicular (that is, they intersect at a 90° angle).

Looking at the attached graph (where the purple line is y = -2/5x + 8), their lines do not form a 90° angle.

Therefore, the correct answer is neither.

So Length * Width = 480 in. sq.
L=1 1/5 or 1.2W
substitute the L for 1.2W
1.2W*W=480 in sq
divide both sides by 1.2
w*w= 400
W²=400
square root of both sides
Width = 20 inches
Length= (1.2width) or (20*1.2)
Length=24 inches
