Answer: 8.8 pounds.

Step-by-step explanation:

Hi, to answer this question, first we have to divide the total weight loss in a week (28 kg) by 7 (days in a week).

28 /7 = 4 kg per day

The group lost 4 kg each day.

Finally we have to convert the result into pounds.

Since 1 kg = 2.2 pounds

4 kg x 2.2 = 8.8 pounds.

Feel free to ask for more if needed or if you did not understand something.

Answer:

12\sqrt{6} + 8\sqrt{15} + 12 + 4\sqrt{10}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

(4\sqrt{3} + 2\sqrt{2} )(3\sqrt{2} + 2\sqrt{5} )

Each term in the second factor is multiplied by each term in the first factor, that is

4\sqrt{3} (3\sqrt{2} + 2\sqrt{5} ) + 2\sqrt{2} (3\sqrt{2} + 2\sqrt{5} ) ← distribute both parenthesis

= 12\sqrt{6} + 8\sqrt{15} + 12 + 4\sqrt{10}
