You can see it's a geometric sequence because the ratio is constant (

).
The nth term of a geometric sequence:


It has to be the sum for term 4 through term 15, so n=4 and the number above the sigma is 15.

Answer:
12,156,2029
Step-by-step explanation:
A function with zeroes at z1 and z2 can be factored into form
f(x)=a(x-z1)(x-z2)
where a is a constant
so
it is
f(x)=a(x-(-4))(x-2) or
f(x)=a(x+4)(x-2)
Answer:
230
Step-by-step explanation:
17*10=170
12*10*1/2=60
170+60=230
H will equal 4 I hope this helps.
