Answer:
x=9
Step-by-step explanation:
1. distribute the 3 to x and -2 : 3x-6
2. Next add 6 to both sides : 3x-6=21
3. that answer will be 27 so your left with : 3x=27
4. Divide both sides by 3 and x=9
We can assume that it is aline
y=mx+b
m=slope
b=yintercpt
if you have th epoints (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
pick any 2 points
(1,2) and (2,5)
slope=(5-2)/(2-1)=3/1=3
y=3x+b
solve for b
sub a points
(x,y)
(0,-1)
-1=3(0)+b
-1=0+b
-1=b
the equation is y=3x-1
or infunction form
f(x)=3x-1
First, we pass the other number subtracting, like this:
Then we pass the number 3 dividing, like this:
So, the answer is: W = -3.

Answer:
24cm^2
Step-by-step explanation:
Given data
Length= 6cm
Width=4cm
Required
The area of the Rectangle
Area=Length*Width
Substtiute
Area=6*4
Area= 24cm^2
No.
The maximum possible area given a constant amount of material for a quadrilateral will always be a square.
For example if the material for the perimeter is 64 we can form a rectangle that is 22 by 10 which will have an area of 220 u^2.
However a square using the same amount of material will have sides of 64/4=16 and an area of 16^2=250 u^2
So in general the area is maximize the closer the sides are to being equal and minimized as the difference between the sides becomes greater. In the case of comparing the material, perimeter, of a rectangle to a square for the same amount of material the square will use less material than the rectangle.
A square can have a smaller perimeter and a greater area that a rectangle.
In the example above the rectangle had a perimeter of 64 u and an area of 220 u^2. If we made a square with just 60 u, it would have an area of 225 u^2.
