Answer:
5
Step-by-step explanation:
Okay, so adding negative numbers can get very tricky, but I think I can help
Since there are two negative signs next to each other, they both cancel out and become positive so instead you get
-2+7
And if you do this with a number line, if you start and negative 2 and keep going right 7 times, you get 5
I hope I helped! I know negative numbers can be really difficult, but once you get the hang of it I bet you'll be great!
Answer:
here, you are simply asked to find perimeter
so add all sides to find it. soln is below
a+5+2a-1+3a-7 = 6a-3= 3(2a-1) ans
Both x and y must be rational.
Answer:
r = 2
Step-by-step explanation:
nth term of a geometric sequence = .
Where,
a = first term, r = common ratio,
We are given that, the 11th term is 32 times larger than the 6th term of the geometric sequence. Thus:
the 6th term can be expressed as
The 11th term is expressed as
Since the 11th term is 32 times larger than the 6th term, therefore, the following equation can be derived to find the common ratio, r, of the sequence:
, therefore:
Divide both sides by ar⁵
Common ratio = 2
