Answer:
The second one.
Step-by-step explanation:
Answer:6
Step-by-step explanation:
$220 × 6 = $1320 this is how much it cost to pay 6 carpenters for one day. Now lets find how much it cost to 12 plumbers at $260 a day. $260 × 12 = $3120 this is how much it costs to pay 12 plumbers a day.
Complex roots occur when b^2 - 4ac is negative.
So we have (-6)^2 - 4.1.k < 0
-4k < - 36
k > 9
I believe the answer is 24.You do 12 divided by 3 and then you get 4. Then you do 4 times 6 and get 24.
