Answer:

9:15 am

Step-by-step explanation:

Alarms sound at 7:15 am

Alarm frequencies are 40 min and 60 min

Since 40= 20*2 and 60= 20*3, the overlapping frequency is:

20*2*3= 120 min = 2 hours

So next time both alarms sound at 7:15 am + 2 hours = 9:15 am

Answer:

x = 0, x = $\frac{3}{2}$

Step-by-step explanation:

Given

8x² - 12x = 0 ← factor out 4x from each term

4x(2x - 3) = 0

Equate each factor to zero and solve for x

4x = 0 ⇒ x = 0

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = $\frac{3}{2}$
