Aria needs to work out how many fish can be put in the pond. She wants have both Koi fish and Goldfish.

The number of fish is based on the surface area of the water in the pond.

Koi Fish need 12^2 m each
Goldfish need 0.6^2 m each.

Aria wants to have a mixture of Koi fish and Goldfish in the ratio 1:4

What is the maximum number of Koi fish and Goldfish that Aria can put in the pond, if she keeps the ratio 1-4?

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

step-by-step explanation:

it's both, now can you answer my most recent question?

step-by-step explanation:

compare

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
