Step-by-step explanation:

<em>The question is mixed up with another (See comment for correct question)</em>

Given

Length = 799in

Width = 245in

Required

The perimeter of the deck (this is what the question implies)

The perimeter (P) is:

P =  2 * (Length + Width)

P =  2 * (799 + 245)

P =  2 * 1044

P =  2088

The function f(x) is a quadratic function and a limited table of values is provided below. Write the equation of the quadratic p
OverLord2011 [107]

Answer:

  f(x) = 3x^2 -21x +36

Step-by-step explanation:

The table gives the x- and y-intercepts, which are sufficient to write the equation in factored form. The x-intercepts of 3 and 4 tell you that factors are (x -3)(x -4). When x=0, this product is (-3)(-4) = 12, but the y-intercept value is 3 times that: 36. So, the factored equation is ...

  f(x) = 3(x -3)(x -4)

Multiplying this out, we get ...

  f(x) = 3(x^2 -7x +12)

  f(x) = 3x^2 -21x +36
