Given:
3 pepperoni pizza for every 2 cheese pizzas sold
12 cheese pizzas sold.

This is a proportion problem:

3 : 2 = x : 12

a : b = c : d  where ad = bc

a = 3 ; b = 2 ; c = x ; d = 12

3 * 12 = 2 * x
36 = 2x
36/2 = 2x/2
18 = x

18 pepperoni pizzas are sold during the 20 minute period.

PLEASE HELP IM SO STUCK ILL MARK YOU BRIANLIEST!!! 30 POINTS Given the expression: 6x10 − 96x2 Part A: Rewrite the expression by
Murljashka [212]

Answer:

6x^2 ( x^2 -2) ( x^2 +2)(x^2+2x+2)(x^2-2x+2)

Step-by-step explanation:

6x^10 − 96x^2

Factor out 6x^2

6x^2 ( x^8 - 16)

Notice that inside the parentheses we have the difference of squares

6x^2 ( x^4 ^2 - 4^2)  a^2 - b^2 = (a-b) (a+b)

6x^2 ( x^4 -4) (x^4 +4)

Notice that x^4-4 is also the difference of squares

6x^2 ( x^2^2 -2^2) (x^4 +4)

6x^2 ( x^2 -2) ( x^2 +2) (x^4 +4)

Note also that x^4 + 4 can be factored into (x^2+2x+2)(x^2-2x+2)

6x^2 ( x^2 -2) ( x^2 +2)(x^2+2x+2)(x^2-2x+2)
