Answer: \sum^{24}_{n=1} (4n+5)

Step-by-step explanation:

This is an arithmetic series with a common difference of 4, so we can immediately eliminate the two left-hand options.

To determine which of the two options on the right is correct, we can determine the first term of each sum expanded out.

  • For the top right, the first term is 4(0)+5=5, which does not match the first term of the given sequence.
  • For the bottom right, the first term is 4(1)+5=9, which does match the first term of the given sequence.

Answer:

x = 9

m Angle B = 54

m Angle E = 54

Step-by-step explanation:

As m Angle B and m Angle E are congruent,

5x + 9 = 7x - 9

-2x = - 18

x = 9

m Angle B = 5x + 9 = 54

m Angle B = m Angle E

Therefore, m Angle E = 54
