Answer:

D: 6√30

Step-by-step explanation:

Simplify the following:

sqrt(20) sqrt(3) sqrt(18)

sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):

sqrt(20) sqrt(3)×3 sqrt(2)

sqrt(20) = sqrt(2^2×5) = 2 sqrt(5):

2 sqrt(5) sqrt(3)×3 sqrt(2)

2×3 = 6:

6 sqrt(5) sqrt(3) sqrt(2)

sqrt(5) sqrt(3) sqrt(2) = sqrt(5×3×2):

6 sqrt(5×3×2)

5×3 = 15:

6 sqrt(15×2)

15×2 = 30:

Answer: 6 sqrt(30)

A 12- pack of 8- ounce juice boxes costs $5.90. How much would an 18- pack of the same 8- ounce juice boxes cost?

stira [4]

Answer:

$8.85

Step-by-step explanation:

This a question of direct variation, so we can make out a relationship between the two factors. 12 is 2/3 of 18, so the cost of 12 would also be 2/3 of the cost of 18. We can now make an equation to solve.

$\frac{2}{3} x=5.9\\2x=17.7\\x=8.85$
