Multiply equation II by 2 and then add up the equations.
One pizza serves four people so, you will need 10 pizzas for 40 people so that make the answer (A.)
Answer:
When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.
I'm not entirely sure what you're looking for, but here are your options. If you need a perfect square, I'd go for the 12 and 12, but I hope this helps?
that is the sum of the interior angles of a triangle,or the 3 sided polygons
