Find the axis of symmetry of 2x^2 + 12x + 16 Show your work

raketka [301]

The vertex form:

$y=a(x-h)^2+k\\\\(h,\ k)-vertex$

The axis of symetry is x = h.

$y=ax^2+bx+c\to h=\dfrac{-b}{2a}$

We have

$y=2x^2+12x+16\to a=2,\ b=12,\ c=16$

Substitute:

$h=\dfrac{-12}{(2)(2)}=\dfrac{-12}{4}=-3$

<h3>Answer: x = -3</h3>

Measuring the figure with a ruler, length = 2 inch and width = 1.5 inch

It is given that 1/2 inch = 4 feet

1 inch = 4*2 = 8 feet

Area of rectangle = length * width

Length = 2*8 = 16 feet

Width = 1.5*8 = 12 feet

Area of Quintoe's bedroom = 16 feet * 12 feet = $192 feet^2$

Hence option C is correct.
