First, replace the numerator with the parentheses.
Second, multiply both sides by 3.
Third, multiply 2 × 3 to get 6.
Fourth, take away 15 from each side.
Fifth, simplify -6 - 15 to get -21.

Answer:
n = -21
Answer:
A right angle is neither Obtuse nor Acute
Step-by-step explanation:
You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row
An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row
now use a sum sequence to find total number of seats
Sn = n(a1 + an)/2
Sn = 24(4+119)/2
Sn = 24(123) /2
Sn = 1476 total seats
To triple, means to multiply that number by 3.
To cube means to times that number by it's self three times.
So, in conclusion, the answer would be Kayla.
