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:
(5, -3)
Step-by-step explanation:
let (x1, y1) = (6, -7) and (x2, y2) = (4,1)
(Xmidpoint, Ymidpoint) = ( (x1+x2) / 2, (y1+y2) / 2)
= (5, -3)
Answer:
The correct answer is c. f(x) = 1/(x + 4)
Step-by-step explanation:
We can tell this because as the bottom of the equation (x + 4) approaches 0, the equation gets larger and larger.
Also, you can note that -4 is a asymptote, which can only be from the bottom of the equation being equal to 0. This is only true in option c.

Fill in the gap using 1 to 9 to give a result close to 0
First, you have to determine what kind of numbers that are close to 0;
In this case, I'll work with -0.4 to 0.4 because the number in this range approximate to 0;
Next, is to fill in the gaps using trial by error method

Answer:
![-3x^2-42x](https://tex.z-dn.net/?f=-3x%5E2-42x)
Step-by-step explanation:
<em>Distributive property:</em>
<em> ↓</em>
<em>A(B+C)=AB+AC</em>
<em />
<em>A=-3x, B=x, and C=14</em>
<em />
<em>-3xx+(-3x)*14</em>
<em />
<em>(-b)+=-b</em>
<em />
<em>-3xx-3*14x</em>

<em>Simplify to find the answer.</em>
<em />
<em>-3xx-3*14x=-3x^2-42x</em>
