Answer:
x=12
Step-by-step explanation:
Using Proportion:
3*3=9
3 *-8i = -24i
8i *3 =24i
8i*-8i = -64i^2 or i^2 =-1. -64*-1=64
-24i + 24i =0
9+64= 73
Answer 73
Answer:
A minimum of 16 rows are needed
Step-by-step explanation:
Here, we want to calculate the number of rows minimum that could seat 382 people in rows of 24 seats.
Mathematically, what we need to do here is to make a division.
We shall divide the number of people by the number of seats in a row so that we can get the number of rows needed.
Mathematically, that would be; 382/24 = 15 22/24
We are looking at a minimum number.
So we can see that 15 rows will be filled, with an extra 22 seats in the next row leaving only 2 seats in the next row unoccupied.
So we can see that the minimum number of rows required is 16 rows
The answer is : (3x-1)(x+4)
