Step-by-step explanation:

I am going with A12x + 7yx = # of adult and y = # of childrenadults cost 12 and children cost 7 <

B doesn't make much senseu could say x was for girls and y for boys...but u already know how many there areso I am not sure what the x and y could stand for.

C does't make much sense eitherx would have to be red marbles and y would have to be green marbles...but just like B, u already know how many there areso not sure what x and y could stand for

D. wrongbecause the box containing x 7 oz packages and y 12 oz packages12x + 7yfor this one to be correct, it would have to have x 12 oz packages and y 7 oz packages

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
