Answer:
1
Step-by-step explanation:
9 - 4 x 2
4 x 2 = 8
9 - 8 = 1
Answer:
The function f(x) when x=x-4 is
or 
Step-by-step explanation:
Given function f is defined by 
Now to find the function f(x-4):

Put x=x-4 in the above function we get

(using the formula
)

(adding the like terms)


Therefore
or 
The function f(x) when x=x-4 is
or 
1,2,4,8
those are the factors of 8
X=3
y=1
Use substitution method starting with the first equation substitute y in the second equation
Given:
Area of rectangle = 
Width of the rectangle is equal to the greatest common monomial factor of
.
To find:
Length and width of the rectangle.
Solution:
Width of the rectangle is equal to the greatest common monomial factor of
is



Now,

So, width of the rectangle is
.
Area of rectangle is

Taking out GCF, we get

We know that, area of a rectangle is the product of its length and width.
Since, width of the rectangle is
, therefore length of the rectangle is
.
