To find the circumference, you have to multiply 2 by 2 and pie. 2 x 2 is 4. So 4 times pie. B is your correct answer.
I hope this helps :)
Answer:
<em>B. (U+V)(U-V)</em>
Step-by-step explanation:
<u>Factoring</u>
The given expression is:
It should be noted that both terms are perfect squares:
Since it's a difference of squares, we need to use the following pattern to factor the required expression:
Thus, the answer is
B. (U+V)(U-V)
Answer:
after 4 hours she cycled 48+ 20 which is 68 miles
Step-by-step explanation:
The easiest way to find the LCM is to keep listing multiples until you find a common one.
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84
Multiples of 12:
12, 24, 36, 48, 60, 72, 84
84 is the LCM
Mean=average=sum of terms/number of terms...
(25+17+38+11+24)/5
115/5
