Answer:
0.64 kilometres
Step-by-step explanation:
<u>Step 1: Find the perimeter in metres</u>
Perimeter of square = 4 x (Length)
Perimeter = 4 (160)
Perimeter = 640 metres
<u>Step 2: Convert from metre to kilometre</u>
1 km = 1000 m
x km = 640 m
<em>Cross multiply</em>
1000x = 640
x = 0.64 kilometres
Therefore, the perimeter of the square base is 0.64 kilometres.

Answer:
y=-3x-12
Step-by-step explanation:
Plug into equation y=mx+b
3=(-3)-5+b
Simplify
3=15+b
Subtract 15 from both sides
-12=b
Add slope and y-intercept into base equation
y=-3x-12
Answer:
−1(5−2)(5+2)
Step-by-step explanation:
Eliminate redundant parentheses
