dangina [55]

Answer:

Total no of ways can a combo containing 2 burgers, 3 different sides, 2 different flavor drinks, and 3 ice cream flavors be made = 529,200

Step-by-step explanation:

Given -

A fast-food restaurant offers 6 different burgers, 6 different side orders, 7 different flavor drinks, and 9 different flavors of ice cream .

choose 2 burgers from 6 different burger = $\binom{6}{2}$

choose 3 different sides from 6 different side orders = $\binom{6}{3}$

choose 2 flavor drinks from 7 different flavor drinks = $\binom{7}{2}$

choose 3 ice cream from 9 different flavors of ice cream = $\binom{9}{3}$

Total no of ways can a combo containing 2 burgers, 3 different sides, 2 different flavor drinks, and 3 ice cream flavors be made=

= $\binom{6}{2}\times\binom{6}{3}\times\binom{7}{2}\times\binom{9}{3}$ ( Using combination )

= $\frac{6!}{(2!)(4!)}\times\frac{6!}{(3!)(3!)}\times\frac{7!}{(2!)(5!)}\times\frac{9!}{(3!)(6!)}$

= $15\times20\times21\times84$

= 529,200

Answer:

$- 8 {y}^{3} + 6 {y}^{2}$

Step-by-step explanation:

$2y^2(-6y + 3) + 4y^3 \\ \\ = - 12 {y}^{3} + 6 {y}^{2} + 4 {y}^{3} \\ \\ = 4 {y}^{3} - 12 {y}^{3} + 6 {y}^{2} \\ \\ = - 8 {y}^{3} + 6 {y}^{2}$
