Let the number of rows be = r
Let the number of seats per row be = s
we know that the number of seats is 126.
So, 
..... (1)
As given, there are five more seats per row than the number of rows, so we can say that:
Putting this in equation (1)
r=-14 and r=9 (neglecting the negative value) we get r=9
And s=r+5
so, s =9+5=14
Hence, there are 5 rows and 14 seats per row.
Answer:
-3.75
Step-by-step explanation:
the opposite changes the sign from positive to negative, so the opposite of 3.75 would be -3.75
Hi there!
The formula for the area of a triangle is A = 1/2(b x h). Using the information provided, all we have to do is plug in what we know and solve!
WORK:
74 = 1/2(b x 9.14)
148 = b x 9.14
b = 16.2 inches (approximately)
Hope this helps!! :)
