Answer:
a) 10*10 inch, b)yes, c) 15
Step-by-step explanation:
a)
we need to calculate the Greatest Common Factor between 30 and 50

then, the square tiles will be 10 inch *10 inch
b) it will change because they don't need to have the largest slab possible so they will use any other comon factor with a size they consider correct for the cheese.
c)

15 squares of 10inch*10inch of cheese could be cut.
Answer choices? I can try and figure it out if there are choices
When we want to find the roots of a one-variable function, we look for where its graph intersects the x-axis. In this case, the graph intersects the x-axis at 
The vertex of a parabola is the highest or lowest point on it, depending on whether the leading coefficient of the quadratic function is negative or positive. In this case, we see that the lowest point is 
For the y-intercept, just look for where the graph intersects the y-axis; in this case, that point is 
Using this information, the vertex-form equation of the parabola is
so the factors are two copies of
In this case, the value of
in the equation
was conveniently 1; if that's not the case, you'll want to plug in
to solve for the value of a that gives the correct y-intercept.
Does that help clear things up?
The y-intercept would represent the highest point. The graph will show a parabola and this point will only be reached once.
The x-intercept would be the starting point and the ending point. You can find total distance traveled with this.
