Answer:
The cube must be 21.125 feet long.
Step-by-step explanation:
David can completely cover a cube of side length equal to 2 feet, using 16 quarts of paint.
With this we make a conversion factor:
feet/quarts = 0.125 feet/quarts
This means that with each quart of paint you can paint a 0.125-foot long cube
We need to know how big is the length of a cube that can be covered with 169 quarts of paint
Then we use the conversion factor found earlier

The cube must be 21.125 feet long.

Answer:
Step-by-step explanation:
Any side to side movement of a function will be reflected inside a set of parenthesis with the x. For example, if the function was a parabola, the parent graph could be, very simply,

Side to side movement would make the equation look like this:

where h is the x coordinate of the vertex.
Up or down movment would make the equation look like this:
for movement upwards, or
for movement downwards. The k represents the y coordiante of the vertex in this parabola.
Because our function has NO numbers inside the parenthesis with the f(x), but it has a -1 after, we are moving the parent graph of this function, whatever it is, down one from its starting position.
Sqrt(x+12)=x
*square root both sides
x+12=x^2
*subtract over x and 12
x^2-x-12=0
*factor using diamond method
(x-4)(x+3)=0
x=4,-3
