11 - 3m (replace m with 2)
11 - 6
5
The answer is
A. 5
Since it is a geometric sequence each term will be a specific multiple of the term preceding it, called the common ratio...
126/42=378/126=1134/378=3
The sequence is a(n)=a(3)^(n-1) and we know the second term is 42 so:
42=a(3)^(2-1)
42=3a
a=14
So the first term is 14.
Answer:
Step-by-step explanation:
The trick is to find the third angle
180 - A - <BCA = <CBA
180 - X - <BCX = <CBX
Everything else is OK
<CBA = <CBX Equals equated to an equal express = an equal expression.
Now by a little slight of hand, you get the two triangles to be equal by ASA, which always works.
Cheating you say? There is no such thing as cheating if it correct and it works.
Answer:
0.3 miles.
Step-by-step explanation:
If it takes all 3 of them to get there in a mile then it will equal to 3 miles.
11*11 is 121 so if you round one of this 11’s up to 11.364 you get just over 125
