Answer:
Step-by-step explanation:
Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make flowers in an hour.
The groups decided to work together. They can make together in an hour and it takes them hours. Group B took a break for 1 hour and 40 minutes ( hour), then Group B works
hours.
Thus,
Before you use the quadratic formula, you have to make sure the equation itself is a quadratic and that a and b are not 0.
It’s the third answer
(2x + 5) x ( 3x -4)
Remember the arc is equal to the central angle, so ab will equal angle APB. they told you angle APB is a right angle, how many degrees is this? that is what ab will be also:)
