The initial age of 10 years and the spaceship speed of 0.60•c, gives the Andrea's age at the end of the trip as 18 years.
<h3>How can Andrea's new age be calculated?</h3>
The time dilation using the Lorentz transformation formula is presented as follows;
From the question, we have;
The spaceship's speed, <em>v</em> = 0.6•c
∆t = Rest frame, Courtney's time, change = 10 years
Therefore;
The time that elapses as measured by Andrea = 8 years
Andrea's age, <em>A</em>, at the end of the trip is therefore;
A = 10 years + 8 years = 18 years

Answer:
4
Step-by-step explanation:
Remark
The upper answer is correct. Any time you are dealing with addition or subtraction and one of the numbers is irreducible and remains irrational no matter what you do, then the entire addition or subtraction of terms remains irrational.
For the second one that you did not answer, it works the same way as the comment says.
3√2 * 8√18 give two numbers that can be multiplied under the square root sign.
3*8 = 24
√(2*18) = √(36) = 6
The answer is 24*6 = 144
This procedure is the only way I know that you can get a rational result from two irrational factors. In fact it is really quite useful to know. You will use this when you learn how to rationalize the denominator. This exact method is used to do that.
- 3x + 4y = 6 and 3x + 4y = 10 are an example for which Ariel’s claim is true.
- 3x + 4y = 6 and 3x + 4y = 6 an example for which Ariel’s claim is false.
- An improvement to Ariel’s claim is adding the phrase "and the independent variables are different" to her conditional statement.
<h3>What are parallel lines?</h3>
Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
<h3>The condition for two
parallel lines.</h3>
In Geometry, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts. This ultimately implies that, two (2) lines are parallel under the following conditions:
m₁ = m₂
<u>Note:</u> m is the slope.
<h3>What is a conditional statement?</h3>
A conditional statement can be defined as a statement that can be written to contain both a hypothesis and conclusion. Thus, it typically has the form "if P then Q."
Based on the given conditional statement, an example for which Ariel’s claim is true is given by:
- 3x + 4y = 6
- 3x + 4y = 10
Based on the given conditional statement, an example for which Ariel’s claim is false is given by:
- 3x + 4y = 6
- 3x + 4y = 6
An improvement to Ariel’s claim is adding the phrase "and the independent variables are different" to her conditional statement.
