This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
Answer:
Step-by-step explanation:
s:m = 7:5
s = 7x, m = 5x
(7x+10):(5x+10) = 9:7
(7x+10)/(5x+10) = 9/7
7(7x+10) = 9(5x+10)
49x+70 = 45x+90
x = 5
s = 7x = 35, m = 5x = 25
Sonu is 35, Monu is 25
The answer is 4 hope this helps
