Lets solve your equation step by step:
(4k + 5)(k + 1) = 0
Step 1: Simplify both sides of the equation:
4k^2 + 9k + 5 = 0
Step 2: Factor left side of equation:
(4k + 5)(k + 1) = 0
Step 3: Set factors equal to 0:
4k + 5 = 0 or k + 1 = 0
k = - 5/4 or k = - 1
Answer: k = - 5/4 or k = - 1
Hope that helps!!!! ( Answer: k = -5/4 or k = -1)

Answer: 14 tickets weren't sold.
Step-by-step explanation:
14 times 15 = 210
So there are 210 seats in the cinema.
The total is $1274 so you would divide
which equals 196
Your final step is to subtract
210 (the total seats) minis 196 (seats sold) equals 14 seats not sold
