Answer:
d. 18x^3-27x^2y
Step-by-step explanation:
(3x)^2(2x-3y)
work out the first term
9x^2(2x-3y)
distribute
18x^3-27x^2y
<h3>Given :-</h3>
- Pranav ran 20.3 km more than Branda

To find :
- No. of kilometers did Brenda run.

<h3>Let :</h3>
- No. of kilometers ran by Brenda be x.

<h3>Solution:</h3>

Equation formed:-

Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.
Therefore:-


Write the equation


When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)


Arrange the equation because x is always represented at left side.


After subtracting 38.6 with 20.3 we will get result as 18.3 .


In the algebraic expression a constant is a fixed value, and in this case it is 4. If the question was asking for the coefficient, then the answer would’ve been 7 due to to variable being multiplied.
