<h3>
How to calculate the coordinate of point by reflection</h3>
A point if reflected across the line
by means of the following formula:
(1)
Where:
- Original point
- x-Coordinate of point P
- Resulting point
If we know that
and
, then the coordinates of the vertex is:
![P'(x,y) = (-2, 4) + 2\cdot [(-2,-2)-(-2,4)]](https://tex.z-dn.net/?f=P%27%28x%2Cy%29%20%3D%20%28-2%2C%204%29%20%2B%202%5Ccdot%20%5B%28-2%2C-2%29-%28-2%2C4%29%5D)



The coordinates of vertex B' is

Answer= x²+7x+10
When we want to expand expressions such as this, the FOIL method helps us remember what exactly to do. FOIL stands for
F:First
O:Outer
I:Inner
L:Last
So, given the expression (x+5)(x+2), lets multiply the first two terms.
x*x=x²
now the outer two terms
x*2=2x
now the inner terms
5*x=5x
and the last terms...
5*2=10
When we combine these expressions we get:
x²+7x+10
I think this is what you meant to be answered in your question, if I have been mistaken, just comment and I'll edit my answer....
Answer:

Step-by-step explanation:
=> 78% makes:
=> 
<u><em>In simplest form:</em></u>
=>
If x=width, then the equation would be:
x(x+10)=20,000
The length is 10 meters longer than the width(x), so the length is x+10.
To get the area(20,000) you multiply width by length, hence x(x+10).
Hope this helps.
