Need help on this! Please someone help!!!
Jet001 [13]

This can be easily solved, especially with a calculator.
With the calculator, you can find that \sqrt{42} is about 6.4807.
Multiply that by 2, you get about 13 inches.

If you can't use a calculator, then you can just estimate. Since we know that \sqrt{36} is 6 and \sqrt{49} is 7, \sqrt{42} is in between them, so you can just say somewhere around 6.5.

Multiply 2 * 6.5 and you get 13 inches.

I need help pls it’s a final
algol [13]

Answer:

A.Both of the students did the problem correctly.

Step-by-step explanation:

B. Nikki multiplied the fraction(8/3) to the items in the parentheses. Then multiplied each side with 3. Jon did the opposite. He first removed the fraction by multiplying each side by 3. Then he multiplied 2 to the items in the paranthesis.

C. I prefer Jon's method. Fractions can be tricky. I prefer to remove them as soon as possible. This time the items in the paranthesis had whole numbers. But had any of them been a fraction too, the problem would have gotten a lot more tricky and it would very easy to make a mistake or miscalculate something.
