14x14=196 just add 14 +14 +14 +14 14 +14 14 +14 14 +14 14 +14 14 +14 and get 196
Answer:
see explanation
Step-by-step explanation:
If (2x + 1) is a factor then x = - 
is a root and P(- ) = 0 ← Factor theorem
P(- )
= 2(- )³ - 11(- )² - 4(- ) + 1
= - 
- 
+ 2 + 1
= - 
+ 3
= - 3 + 3
= 0
Since P(- ) = 0 then g(x) is a factor of P(x)
Answer:
Step-by-step explanation:
we can only take common factor
18 and 12 have 6 as a common factor
in variables we have
and 
so we see clearly that it is 
so we have
as far as you can go
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.
Here we are give the initial term so we have to solve to solve for the common ratio...
a(5)=-1280 and a(1)=-5 so
-1280=-5r^(5-1)
-1280=-5r^4
256=r^4
256^(1/4)=r
4=r, so our sequence is:
a(n)=-5(4^(n-1)), so the 7th term is:
a(7)=-5(4^6)
a(7)= -20480
