Answer:
c = 9
Step-by-step explanation:
<span>numbers of seats in a row makes an arithmetic series
chairs in the nth row
an = 4 + 23*5 = 119
and the sum is
sn = (4 + 119) * 24/2 = 1476</span>
Answer:
8
Step-by-step explanation:
rows=x
each row=(x+5) tomatoes
she increased the number of rows by 3
and doubled the number of tomatoes in each row
3multiplied by x=3x
(2x+10) because she doubled them
3x+10÷2x
=8

If one square is divided into 9 smaller equal squares, then they have to be arranged in 3 lines of 3, that is 3 smaller equal squares per side of the original big square. That said, the area of the big square is equal to the multiplication of 3 small squares sides times 3 small squares sides, call x the length of the small squares.
So,
area = 9 = 3x*3x
9x^2 = 9
x^2 = 1
x = 1
therefore the smaller squares have sides of 1 unit
