Answer:
r = 8
Step-by-step explanation:
The common ratio r of a geometric sequence is
r =
=
= ..... = 
Then
r =
=
= 8
Answer:
Yes
Step-by-step explanation:
2(x + 7) = 2x+14
First we find the scale factor. It went from a 11 cm length to 16.5 cm length....so we have to find out what to multiply 11 by to get 16.5.
11x = 16.5
x = 16.5 / 11
x = 1.5
and since we multiplied 11 * 1.5 = 16.5, then we have a scale factor of 1.5...so we now multiply the height of 4 by 1.5.
So the new height is gonna be : 4 * 1.5 = 6 cm <==
- 3.4 > - 4.2 is the only correct statement
> means larger than
< means smaller than
A negative number which closer to 0 than an other negative number, is larger. Therefore - 3.4 is larger than - 4.2, and therefore - 3.4 > - 4.2
