Answer:
1km=1000m 160m=0.160x4=0.64
Step-by-step explanation:
Ifl = 160m, then:
P = 4 * 160m\\P = 640m
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition: 1Km = 1000m
By making a rule of three we have:
1Km ---------> 1000m
x --------------> 640m
Where "x" represents the perimeter of the base of the pyramid in Km.
x = \frac {640 * 1} {1000}\\x = 0.64km
(w - 7)(w + 4)
w^2 - 7w + 4w - 28
w^2 - 3w - 28

Answer:

Step-by-step explanation:
Given
Perpendicular to 
Pass through 
Required
Determine the line equation
First, we need to determine the slope of 
An equation is of the form:

Where

In this case:

Next, we determine the slope of the second line.
Since both lines are perpendicular, the second line has a slope of:



Since this line passes through (-2,2); The equation is calculated as thus:

Where

This gives:



Add 2 to both sides
