Answer:

Step-by-step explanation:
I = prt
Switch sides.
prt = I
We are solving for p. We want p alone on the left side. p is being multiplied by r and t, so we divide both sides by r and t.


This is a difference of squares, meaning that when you multiply the binomials it would be the front term squared minus the last term squared.
The front term squared = (3A) squared = 9A squared
The last term squared = (4B) squared = 16B squared
Final Answer: D. 9A squared - 16B squared
<em>3</em><em>9</em><em>></em><em>3</em><em>8</em>
<em>1</em><em>6</em><em>=</em><em>1</em><em>6</em>
<em>1</em><em>1</em><em><</em><em>3</em><em>1</em><em>5</em>
<em>5</em><em>></em><em>4</em>
