Answer:
<u>131 seats</u> are in the 30th row.
Step-by-step explanation:
The theater is designed with the first row there are 15 seats, in second row 19 seats and in the third row there are 23 seats.
Now, to find the number of seats in the 30th row.
So, we get the common difference(
) from the arithmetic sequence first:
Thus, 
So, the first tem 
= 15.
The number of last row (
) = 30.
Now, to get the number of seat in the 30th row we put formula:
Therefore, 131 seats are in the 30th row.
The first step to solving this problem is to plug in 6 where you see a in the expression
-6² - 6 (-6) + 4
the first step to solving this is to evaluate the power
-36 - 6x (-6) + 4
next you will multiply the numbers
-36 + 36 + 4
finally,, eliminate the opposite of the expression to find your answer
4
this means that the correct answer to your question is 4.

Answer:Volume = 108 cm ³
Explanation:For a square pyramid, the volume can be calculated as follows:
Volume =
* area of base * height
Volume =
* side² * height
We have:
side length = 6 cm
height = 9 cm
Therefore:
Volume =
* 36 * 9 = 108 cm ³
Hope this helps :)
