They are going to have a little 1.
This means that (x-6)(x+2) = f(x) is the equation for the parabola due to that if you plug these in, when x=6 and x=-2 then y=0. Expanding it, we get
x^2+2x-6x-12=x^2-4x-12. Since the x coordinate of the vertex is -b/2a, it's 4/2=2
Basically you take the different kinds of crusts you can get and multiply that by the different toppings you can get. So
3 X 5 = 15
The answer is D
Hope this helps !
The answer is B because Chris and three of his friends is 4. Then, each person paid $9 so 4 x 3 = x.
8/11--------> 16
to find the total number of fish, divide 16 by 8 and multiply it by 11,
16÷8=2
2×11=22
total number of fish= 22
check,
22÷11×8=16
if you want to find the number of fish without the red stripes,
8/11--------> 16
11/11------->22
3/11--------->?
you can either subtract 16 by 22=6
or
22÷11×3=6
hope this helps......
