Hello :
<span>common ratio of a geometric sequence is : r = (an+1)/(an)
for exemple </span><span>a geometric sequence: 3,6,12,24
r= 24/12 = 12/6= 6/3 = 2</span>
Answer:
{10, -4}
Step-by-step explanation:
(x-3)^2 = 49
Take the square root of each side
sqrt((x-3)^2) = sqrt(49)
x-3 = ±7
Add 3 to each side
x-3+3 = 3±7
x = 3±7
x = 3+7 and x = 3-7
x = 10 x = -4
The forth one is correct hope this helps :)))
It equals 276 but about 300
I think 20×5=100 then 100÷2
