<h2>
Why?</h2>
Discarding each given option in order to find the correct one, we have:
<h2>
First option,</h2>
The statement is false, the correct form of the statement (according to the property of roots) is:
<h2>
Second option,</h2>
The statement is true, we can prove it by using the following properties of exponents:
We are given the expression:
So, applying the properties, we have:
Hence,
<h2>
Third option,</h2>
The statement is false, the correct form of the statement (according to the property of roots) is:
<h2>
Fourth option,</h2>
The statement is false, the correct form of the statement (according to the property of roots) is:
Hence, the answer is, the statement that is true is the second statement:
Have a nice day!
The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:
Since the length is twice the width, we have , and the formula for the perimeter becomes
So, we have
Answer:
D.68ft
Step-by-step explanation:
The building is 231.7 m far away.Distance can refer to a physical length or an estimate based on other factors in physics or common use.
<h3>What is distance?</h3>
Distance is a numerical representation of the space between two objects or locations. |AB| is a symbol for the distance between two points A and B.
Given data;
Speed of sound = 331 meters per second
Time = 0.7 sec
The distance from the building is;
d=v×t
d=331 m/sec × 0.7 sec
d=231.7 m
Hence the building is 231.7 m far away.
