Solve square root of x+3 = 2

Mathematics

AnnZ [28]3 years ago

Answer:

If you mean the square root of (x+3) here's the answer: x=1

Step-by-step explanation:

Pretend there's a square root over x+3:    (x+3)^2=2^2

First eliminate the square root by squaring both sides.

The square root is cancelled so you get

x+3=4

x=1

√x+3 = 2

First we should simplify the equation by squaring both sides:

x + 3 = 4

Isolate x by taking 3 off both sides:

x = 1

We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:

√x + 3 = 2

Turns into:

√1 + 3 = 2

Which turns into:

√4 = 2

Which is true, therefore we can confirm:

x = 1

1.425 gallons/bottle.

<h3>Further explanation</h3>

<u>Given:</u>

  • Yasmine bought 6 gallons of apple juice.
  • After filling up 4 bottles of the same juice, she had 0.3 gallons of apple juice left.

<u>Question:</u>

What is the amount of apple juice in each container (or bottle)?

<u>The Process:</u>

Let the amount of apple juice in each bottle as X.

The two steps for obtaining X are as follows:

<u>Step-1:</u> the total amount of apple juice is the initial gallon amount subtracted by the remaining gallon amount.

\boxed{ \ 6 \ gallons - 0.3 \ gallons = 5.7 \ gallons \ }

<u>Step-2:</u> the total amount of apple juice divided by the number of bottles is the amount of apple juice in each bottle.

\boxed{ \ X = 5.7 \ gallons \div 4 \ bottles = \boxed{ \ 1.425 \ gallons/bottle \ } \ }

Let's also consider the following quick steps.

<u>Quick steps:</u>

\boxed{ \ X = \frac{(6 - 0.3) \ gallons}{4 \ bottles} = \boxed{ \ 1.425 \ gallons/bottle \ } \ }

Therefore, the amount of apple juice in each container (or bottle) is 1.425 gallons.
