38.=721.8 it's really just a matter of multiplication. I only have he answer for this one but, y'know, work and whatnot. If you would multiply 3 by 3 than wou would do the same for this problem
Here we are given the x intercepts at x=3 and x=9
So let us try to make quadratic equation for this using given information.
We have factors in the form (x-a)(x-b)
where a and b are x intercepts given to us.
So rewriting in factored form:

Now let us simplify it:

Let us find the vertex now,
For a quadratic equation of the form:

For x coordinate , we have the formula,

So using this formula for our equation,

So x = 6
Answer: The x-coordinate of the parabola's vertex is 6.
Answer:
75 - 52.5 = x
Step-by-step explanation:
is the correct answer.
Answer:
Step-by-step explanation:
length of the rectangle = 2.5 m
breadth of the rectangle = 1.6 m
Perimeter of rectangle = 2( l + b )
= 2 × 4.1
= 8.2 m
Hope this helps
