3 0

Answer:

The correct option is B.

Step-by-step explanation:

The given expression is

\sqrt{x+2}\cdot \sqrt{x-2}

According to the property of radical expression

\sqrt{a}\cdot \sqrt{b}=\sqrt{ab}

Using this property,we get

\sqrt{(x+2)(x-2)}            

\sqrt{x^2-2^2}                 [\because a^2-b^2=(a-b)(a+b)]

\sqrt{x^2-4}

Therefore the correct option is B.

Wendy’s offers eight different condiments (mustard, catsup, onion, mayonnaise, pickle, lettuce, tomato, and relish) on hamburger
julsineya [31]

Answer:

Check the explanation

Step-by-step explanation:

Conclusion: young people like condiments.

First, let's convert things into percentages, since the number in each age category is different. There are 143 in "Under 18", 233 in "18 to 40", 161 in "40 to 60", and 122 in "over 60".

Of the under 18s: 71 of 143 = 49.7% order three or more.

Of the 18-40s: 87 of 233 = 37.3% order three or more.

Of the 40-60s: 47 of 161 = 29.2% order three or more.

Of the 60 and ups: 28 of 122 = 23.0% order three or more.

The older you are, the less likely you are to order lots of condiments.
