Answer:
<u>It takes them 30/11 hours to paint them together.</u>
Step-by-step explanation:
This is known as a work problem (rate * time = work). We are given the individual times for Tom and Huck (6 hours and 5 hours respectively). However, we are not given the rates at which they can paint the fence. Since we know that the total work that they both do individually is 1 (there is 1 job to do), we can calculate the rates at which Tom and Huck paint the fence on their own:
We can isolate R{t} and R{h} to find the rates at which Tom and Huck work:
Now, we can calculate the time it takes for Tom and Huck to work together using the same formula (the combined rate is just the sum of Tom and Huck's individual rates):
Therefore, the time it takes them to paint the fence together is <u>30/11 Hours</u>
2x = 15 + x
First, our goal is to get 'x' to equal something by itself. To do so, we will have to do everything on one side. Let's subtract 'x' from each sides.
Second, our next step is to subtract '2x - x'. Since 'x' is basically considered (1), it will equal 'x'.
Answer:
maximum area is a square
the side of the square would be 52/4 = 13 feet
area = 13*13 = 169 square feet
Hello,
You need to evaluate the equation, so:
3xˆ2+14x+8 --> 17xˆ2+8. Hop this helps!
