Answer:

x=\sqrt{2}, x=- \sqrt{2}

Step-by-step explanation:

Given:

1.2x^2-2.4=0

We need to find roots of the equation.

First we will solve the above equation and then will remove the root for the same.

1.2x^2-2.4=0\\1.2x^2=2.4\\x^2=\frac{2.4}{1.2}=2\\

Now to find the roots we need to square root on both side.

\sqrt{x^2}=\sqrt{2}\\

square and square root gets cancelled we get.

x= \sqrt{2}, x= - \sqrt{2}

Which equation can be rewritten as x + 4 = x2? Assume x greater-than 0 StartRoot x EndRoot + 2 = x StartRoot x + 2 EndRoot = x S
Mila [183]

We have been given an equation x+4=x^2. We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.

Since x is greater than, so we will take positive root on both sides of our given equation as:

\sqrt{x+4}=\sqrt{x^2}

\sqrt{x+4}=x

Upon looking at our given choices, we can see that option C is same as our answer.

Therefore, option C is the correct choice.

At RSM summer camp 100 students had enough food for a 30-days stay. After 2 days 40 new students joined the camp. After that 2 w
omeli [17]

Answer:

"no additional days of food need to be ordered."

Step-by-step explanation:

Suppose initial quantity of food is x units

Assuming each student eats 1 unit of food per day,

x = 30 * 100 = 3000 units of food

In 2 days, food eaten:

100 * 1 * 2 = 200 units

So food left after 2 days is  3000 - 200 = 2800 units

Now, there are 140 students. They stay 2 weeks (14 days) - 2 = 12 more days

So food eaten in 12 days:

140 * 1 * 12 = 1680 units

<u>THus, after total 14 days gone, the amount of food left is:</u>

2800 - 1680 = 1120 units

Half students left, so there are 70 students left for the last 16 days. How much food would they need?

70 * 1 * 16 = 1120 units

And there are exactly 1120 units left. So, no additional days of food need to be ordered.
