Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes
Answer:

Answer:
<em>π∫52(ey3)2dy</em>
The work I did to solve this equation:
Step 1
<em>ln(3x)=2
</em>
<em>3x=2e
</em>
<em>x=2e3
</em>
Step 2
<em>ln(3x)=5
</em>
<em>3x=5e
</em>
<em>x=5e3</em>
Step 3
<em>y=ln(3x)⟺ey=3x⟺ey3=x</em>
Step 4
π∫52(ey3)2dy

Answer: 4x² + 4x - 2 - 
<u>Step-by-step explanation:</u>
You can use either synthetic or long division. I am using synthetic division:
2x + 3 = 0 ⇒ x = 
| 4 10 4 -6
<u>| ↓ -6 -6 3 </u>
4 4 -2 -3 ← <em>-3 is the remainder</em>
↓ ↓ ↓
4x² +4x -2 ← <em>factored polynomial</em>
