To set up an equation for this you can use a variable to represent your unknown (in this case the unknown is how long it will take to frame 54 houses)
We know that 3 houses can be framed in 1 week so you can represent the equation as
3x=54 (3 being the amount of houses framed in 1 week, x being how many weeks it will take to frame 54 houses)
You can isolate X by dividing both sides by 3 (3x/3 = 54/3) which simplifies to
x = 54/3
Answer:
Because you multiplied two same things. So it removes the square root and then just add the coefficients.

ANSWER
EXPLANATION
We want to find the equation of the parabola with a focus at (5, 0)
and a directrix at x = -5.
The distance from the focus to the vertex is the same as the distance from the vertex to the directrix.
This implies that the parabola has its vertex at the origin. This distance is
This parabola has equation of the form
We plug in p= 5 to get
Or
