Answer:

- 4\sqrt{2}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplify \sqrt{18} using this rule

\sqrt{18}

= \sqrt{9(2)}

= \sqrt{9} × \sqrt{2} = 3\sqrt{2}

Then

- 2\sqrt{18} + 2\sqrt{2}

= - 2(3\sqrt{2} ) + 2\sqrt{2}

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

= - 4\sqrt{2}

Problem 37

<h3>Answer: B. 4 & 1/4 gallons</h3>

-------------------

Work Shown:

The 3/4 and 1/2 add up to (3/4)+(1/2) = (3/4)+(2/4) = 5/4 = 1&1/4

The whole part 1 is then added to the other whole parts 1 and 2 to get 1+2+1 = 4

Overall, the grand total is 4 & 1/4

An alternative way is to convert each mixed number to a decimal to get 1&1/2 = 1+1/2 = 1+0.5 = 1.5 and 2&3/4 = 2+3/4 = 2+0.75 = 2.75

Add up those decimals 1.5+2.75 = 4.25

then convert that result to a mixed number: 4.25 = 4+0.25 = 4+1/4 = 4&1/4

================================================
