This is a false statement.

When you are solving using square roots, you need to be aware that answers can be both positive and negative. When we solve this, you see there are two possible answers.

x^2 - 9 = 0

x^2 = 9

x = +/- 3

While 3 is an answer, so is -3. If we square either of those numbers, we get 9, which will satisfy the equation.

Two friends bring lemonade to your cookout. one brings 2.7 liters and the other brings 3.54 liters. how much lemonade do they br
kozerog [31]

The total lemonade the two friends bring to the cookout when one brings 2.7 liters and the other brings 3.54 liters of lemonade is 6.24 liters of lemonade, computed using decimal addition.

The methods we use to add or subtract decimals are as follows:

  1. Vertically align the decimal points. Any necessary zeros should be entered.
  2. Treat the integers as whole numbers when adding or subtracting them.
  3. Align the decimal point with the numbers being added or subtracted so that it sits vertically above the sum or difference.

In the question, we are informed that two friends bring lemonade to the cookout. The first brings 2.7 liters and the second brings 3.54 liters.

We are asked to find the total lemonade brought by them to the cookout.

To find the total lemonade, we add both the decimal quantities following the steps discussed.

    2.7

+   3. 54

Step 1: Adding zeroes:

    2.70

+   3. 54

Step 2:  Treating them as numbers and adding:

    2.70

+   3. 54

________

    624

Step 3: Aligning decimal points:

    2.70

+   3. 54

________

    6.24

Thus, the total lemonade the two friends bring to the cookout when one brings 2.7 liters and the other brings 3.54 liters of lemonade is 6.24 liters of lemonade, computed using decimal addition.
