Answer:
189
Step-by-step explanation:
Since the series is geometric with common ratio r, then
r = 6 ÷ 3 = 2
The terms in the series are twice the previous term, that is the series is
3 + 6 + 12 + 24 + 48 + 96 ← summing the terms gives
sum = 189
Answer:

Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.

My answer:
Given the information:
- box length-15
- box width-10
- box and jar height unknown (h)
- radius of jar-5
As we all know that, the formula used to determine the volume of the box is:
V = the length* the width * the height
In this situation, we have:
V = 15*10*h
= 150h cubic units
V = the base*the height
In this situation, we have:
V = h*π
<=> V =
π = 25πh
=> The volume of the box that is not occupied by the jar
= The volume of the box - The volume of the jar
= 150h - 25πh
= h(150 - 25π)
We choose C
Answer:
The answer is
<h2>2( x + 3)(x - 5)</h2>
Step-by-step explanation:
To factor the expression
2x² - 4x - 30
<u>First factor 2 out of the expression</u>
That's
2( x² - 2x - 15)
<u>Next write - 2x as a difference</u>
2( x² + 3x - 5x - 15)
<u>Factor out x from the expression</u>
That's
2 [ x( x + 3) - 5x - 15 ]
<u>Factor out </u><u>-</u><u>5 from the expression</u>
2 [ x ( x + 3) - 5( x + 3) ]
<u>Factor out x+3 from the expression</u>
We have the final answer as
<h3>2( x + 3)(x - 5)</h3>
Hope this helps you
