Sela's piano lesson starts at 4: 45 pm the lesson is 30 minutes long when does her lesson ends

Sela's piano class will end at 5 : 15 pm

Step-by-step explanation:

Sela's piano lesson starts at 4 : 45 pm.

If we have to calculate the time when her lesson ends we will add the duration of the class in minutes.

After 30 minutes time will be

4 : 45 + 00 : 30 = 4 : 75

Now we know 00 : 75 or 75 minutes means 1 hour 15 minutes

therefore, 4 : 75 will become 5 : 15 pm

Sela's piano class will start at 4 : 45 pm and end at 5 : 15 pm

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
