Mamont248 [21]
This problem is an another case which makes use of the concept of ratio and proportion. The ratio $2.52 per 0.5 gal should be proportional to the price of 4 gallons of milk. Let x be the price,
                      ($2.52 / 0.5 gallon) = (x / 4 gallons)
The value of x is 20.16. Hence, the price of 4 gallons of organic milk is $20.16.

Lapatulllka [165]

Answer:

3 \sqrt{2}

Step-by-step explanation:

-3 \sqrt{2} + 3 \sqrt{8} =

To add or subtract square roots, you must be taking the square roots of the same number. We need to change square root of 8 into a number times square root of 2.

= -3 \sqrt{2} + 3 \sqrt{4 \times 2}

= -3 \sqrt{2} + 3\sqrt{4} \times \sqrt{2}

= -3 \sqrt{2} + 3 \times 2 \times \sqrt{2}

= -3 \sqrt{2} + 6 \sqrt{2}

Now that we have two square roots of 2, we add them like we add like terms.

= 3 \sqrt{2}
