The bakery sold 66 pies.
Explanation: there are 10 pumpkin pies and 16 more cherry pies were sold than pumpkin. So 26 (10+16) cherry pies were sold. And 14 more apple were sold than cherry. So 30 (26+14) apple pies were sold.
10 pumpkin + 26 cherry + 30 apple= 66 pies
Answer:
A and B
Step-by-step explanation:
Quadratic Equations: f(x) = a(bx - h)² + k
Quadratic equations always have a degree of 2. That means that we will always have an x² term. Of the 4 choices, only A and B offer a term of x², making them a quadratic.
Remark
You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen
Solution
let y = x^2
x^4 = x^2 * x^2
x^4 = y * y
x^4 = y^2
Now the expression becomes
y^2 + 8 y - 9 = z
(y + 9)(y - 1) = z
Now put the x^2 back in.
(x^2 + 9) ( x^2 - 1) = z
x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.
Answer
(x^2 + 9) (x + 1)(x - 1)
Ummm....did you mean like what is the answer to 6x100?
