Answer:

Step-by-step explanation:

The perfect whole squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
Less than 30 are:
<h2>1, 4, 9, 16, 25</h2>
If 9 is 1/3 of the problem, then 9 x 3
= 27 would be the answer
<h2>Hello my friend.</h2>
The Pi value is approximately equal to 3.14.
<h2>I hope I have helped a lot.</h2>
Simplifying
30c + -45d
Factor out the Greatest Common Factor (GCF), '15'.
15(2c + -3d)
Final result:
15(2c + -3d)
