The prime factorization number is 280 I got 2.2.5.7
To find the number of seats, let's do it using multiplication!
First, to see how many seats are in one big section of the theatre, multiply 7 groups of seats by 25 seats:
7 x 25 = 175
Now, knowing this, multiply 175 by 4 to get the total number of seats in the theater!
175 x 4 = 700
Therefore, there are 700 seats in the theatre.
Hope this helps!
You said that. 2x - 9 = 7 . . . . .
Add. 9. to each side: 2x = 16 . . . . .
Divide each side by 2 : x = 8
if ya asking for simpliicatio
remember that
