Answer:
<u>Sum of the 8 terms = 69.19</u>
Step-by-step explanation:
The sum of the geometric series is S

Where: a is the first term
n is the number of terms
r is the constant ratio.
For the giving geometric series: 120 - 80 + 160/3 - 320/9 + ...
a = 120 , n = 8
r = -80/120 = -2/3
∴ 
Answer:
-36x+55
Step-by-step explanation:
3(16−4x(3))+7
=(3)(16)+(3)(−12x)+7
=48+−36x+7
next you have to combine like terms
=48+−36x+7
=(−36x)+(48+7)
=−36x+55
