Answer:
A) No, because the greatest common factor is 8y?, and the completely factored form is 8y2(4y2 - 6y + 3).
Step-by-step explanation:
Considering the expression
4y(8y3 – 12y2 + 6y)
From the elements in the parenthesis, 2 and y can still be factored out such that what will be left of each element
8y3/2y = 4y2
12y2/2y = 6y
6y/2y = 3
Hence
4y(8y3 – 12y2 + 6y) = 4y*2y(4y2 - 6y +3)
= 8y2(4y2 - 6y + 3)
2/3 hour = 20 minutes. so therefore 20 / 5 = 4 x3 = 12
3/5 of that time is 12 minutes.
Answer:
2:30 pm
Step-by-step explanation:
In two hours (from 10am), she is 45 * 2 = 90 miles from vacation cabin.
From then on her average is still 45 mph and her husband's is 65 mph. So, husband catches her 20 miles (65-45=20) in every hour.
<em>The husband has to catch up 90 miles. How long would it take if he is catching up at 20 miles an hour?</em>
<em>90/20 = 4.5 hours</em>
<em />
<em>So husband starts at 10am and 4.5 hours form that time is 2.30pm</em>
The answer is -140
Because if subtract all of these you will get -140
