-4x-8>-20
+8 +8
-4x>-12
Divide by 4 on both sides
x<3
Should be A.
Hope this helps.
Answer:
The general form of geometric series is ⇒ 
Where a is the first term and r is the common ratio
The sum of n terms of the geometric series is ⇒ 
For the given geometric series 2, 8, 32, 128
The first term is a = 2
The common ratio r = 8/2 = 32/8 = 128/32 = 4
So, 
And the sum of the given terms:
n = 4
∴ 
Set up a ratio:
10 foot tall elephant / X shadow length = 15 foot tall statue / 18 foot shadow.
Cross multiply:
10 * 18 = X * 15
Simplify:
180 = 15x
Divide both sides by 15:
x = 180 / 15
x = 12
The elephants shadow was 12 feet long.
