Your answer is attached because I could not not write it in text form.
The graph is touching the x-axis at x= 2 and is turning away.
When a graph exhibit such a behavior at a root, we say that the multiplicity of the root is 2. So the roots of the polynomial are x = 2 and x = 2. The factors of the polynomial are (x - 2) and (x - 2)
The polynomial thus can be written as product of its factors as (x-2)(x-2)
So the correct answer to this question is option B
Answer:
Step-by-step explanation:
1/3(x-5)+171=x
or, (x-5)+513=3x ( multiplying both the sides with 3)
or, 3x - x= 513 - 5
or, 2x = 508
or, x = 508/2
or, x= 254

So:
Solve for x in both cases
Hi there!
Answer:
length = 9 kilometres
Width = 12 kilometres
Let's solve this problem step by step!
To find our answer we need to set up and solve an equation.
Let the length of the rectangle be represented by x.
The width of the rectangle can therefore be expressed by 2x - 6.
The area of a rectangle can be found by using the formula:
A = width × length
Plug in the data from the formula
A = x (2x - 6).
Simplify using rainbow technique.
Now we've found the simplified expression that expresses the area of the rectangle. Therefore, we can now set up and start solve the equation.
Subtract 108
Divide by 2.
Rule AB = 0, gives A is 0 or B is 0.
The length of the rectangle, which was represented by x, must be 9 (since it cannot be a negative number).
Length
Width
Answer:
length = 9 kilometres
Width = 12 kilometres
