It will take them exactly 4hours 48 minutes.
<h3>what is rate?</h3>
Rate is a measure of a given quantity against a known or standard quantity.
Analysis:
If Tanya and Tim cleaned the house in 3 hours. Then either of them would clean the house in 2 x 3 = 6 hours.
If their 3 children cleaned the house in 6 hours, then each child would clean the house in = 3 x 6 = 18 hours
Total time for cleaning the house = 18 hours + 6 hours = 24 hours
If the five people were to do it at once then time taken to clean the house = 24/5 = 4.8 hours = 4 hours 48 minutes
In conclusion, the time for 5 people to clean the house is 4 hours 48 minutes

Answer:
(-9, 9)
Step-by-step explanation:
Each coordinate is multiplied by the scale factor.
B' = 3B
B' = 3(-3, 3)
B' = (-9, 9)
I will give you the answer to number 1.
(x+2) . (x+1)
How to solve:
Step-1 : Multiply the coefficient of the first term by the constant <span> 1 • 2 = 2</span>
Step-2 : Find two factors of 2 whose sum equals the coefficient of the middle term, which is <span> 3 </span>.
<span><span> -2 + -1 = -3</span><span> -1 + -2 = -3</span><span> 1 + 2 = 3 That's it</span></span>
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 2
<span>x2 + 1x</span> + 2x + 2
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+1)
Add up the last 2 terms, pulling out common factors :
2 • (x+1)
Step-5 : Add up the four terms of step 4 :
<span>(x+2) • (x+1)</span>
I would say 108 divided by 4 = 27 but I may be wrong
