Answer:

Subtract (remove) 2 x-tiles from both sides.

x = 5

Step-by-step explanation:

According to the rules of equality, you can add or subtract the same number(s) from both sides of the equal sign. Here, it is convenient to subtract the number of tiles that is on the side with the least number of tiles. That means we want to subtract 2 x-tiles from both sides.

The result of doing that is the answer:

x = 5

Answer:

Step-by-step explanation:

What you have here is the factored form of the quadratic

$ax^2+bx+c$

where a is the term representing the pull of gravity, b is the upwards vertical velocity and c is the initial height. If we FOIL that out, we get the equation in a form that is easily analyzed for velocity and initial height.

$y=-5x^2+10x+15$
