3
Step-by-step explanation:
-3x-9=-6x+18
-9x=27
x=3
By definition, the area of a rectangle is:

Where,
w: width of the rectangle
l: length of the rectangle
The total area is given by:

Where,
A1: rectangular wooden board 1
A2: rectangular wooden board 2
Substituting we have:

Rewriting we have:




Answer:
The width is given by:

Answer:

Step-by-step explanation:
If the extreme ends of a line segment AC are A
and C
.
If a point B(x, y) divides the segment in the ratio of m : n
Then the coordinates of the point B are,
x = 
y = 
If the ends of AC are A(-2, 5) and C(2, -5) and a point B divides it in the ratio of m : n = 5 : 1
Therefore, coordinates of this point will be,
x = 
= 
= 
= 
y = 
= 
= 
= 
Therefore, coordinates of the point B are
.
Answer:
14.4 inches to the nearest tenth.
Step-by-step explanation:
The square has area x^2 where x is the length of each side so:
x^2 = 13
x = √13.
The perimeter is the distance all around the square and this is 4x so we have the answer 4 *√13
14.422 inches.
