Answer:
they will blink 4 times at the same time in one minute
Step-by-step explanation:
you have to find the least common multiple of 5 and 3
LCM of 5,3 = 15
So, the two lights will blink together every 15 seconds.
No.of times blinking together in one minute = 60/15 = 4
The volume of the trapezoidal prism having side lengths x, (x+2), (x+4) and height of 2x is 2x³+6x² option first is correct.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of the trapezoidal prism can be given:

Where V = The volume of the trapezoidal prism:
Length of the trapezoid L = x
Top width a = (x+2)
Base width b = (x+4)
Height of the trapezoidal prism h = 2x


Thus, the volume of the trapezoidal prism is
