Answer:
C
The "inverse operation" is just a way of saying "what do you do to isolate the variable". In this case, we isolate y, so we have to move all terms to the right side. To do that, we subtract 12 from each side to there will only be "y" on the left side.
Answer:
25 capsules.
Step-by-step explanation:
We are told that Joan has a prescription for 100 Theophylline capsules. Joan informs the pharmacist that she only has enough money to purchase ¼ of the prescription today.
To find the number of capsules that Joan will pay for today, we will find 1/4 of 100.
Therefore, Joan will pay for 25 capsules today.
The answer is: " -8 √5 " .

Note:

√-8 *√-40 = i√8 * i√40 ; {since: "i" refers to the imaginary number; " √-1 " } ;
= i² * √8 *√40 ;
___________________________
Note:
"√8 * √40 = ? " ;
↔ " √8 = √4 √2 = 2√2 " ;
"√40 = √4 √10 = 2√10" ;
→ "√8 √40 = 2 * 2 * √2 * √10 ;
= 4 * √(2*10) ;
= 4 √20 ;
→ " √20 = √4 √5 = 2√5 ;
→ 4 √20 = 4 * 2 * √5
= 8 √5 ;
→ i² * 8 √5 ;
↔ 8 i² √5 ;
Note: " i² = -1" ;
→ 8(-1) * √5 ;
= -8 √5 .

Hello!
Let's write this as a system of equations.
L=3w
wL=432
Let's plug in our value for L into the second equation, and solve for w.
w(3w)=432
3w²=432
w²=144
w=12
Now, let's plug our w value into the first equation.
L=3(12)
L=36
Therefore, the length is 36 and the width is 12.
I hope this helps!
