8+9+10 = 27
27/3 = 9

4+5+6 = 15
15/3 = 5

This is always so, because the third number has one extra that can be added to the first to make them 3x the same numbers.

Which of the following represents the sum of the series? 6 8 10 12 14 16 18 20 22 24 26
stira [4]

The sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176

<h3>How to determine the sum of the series?</h3>

The series is given as:

6 8 10 12 14 16 18 20 22 24 26

The above series is an arithmetic series with the following parameters:

First term, a = 6

Last term, L = 26

Number of terms, n = 11

The sum of the series is calculated using:

S_n= \frac{n}{2} *(a + L)

This gives

S_n= \frac{11}{2} *(6 + 26)

Evaluate

S_{11} = 176

Hence, the sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176

Which expression represents the surface area?
ohaa [14]

Answer:

2x + 1/2 sq. ft

Step-by-step explanation:

Surface area = 2(lw+wh+lh)

Given

length l = x ft

width w = 1/2 ft

height h = 1/2ft

Substitute

Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))

Surface area = 2(x/2+1/4+x/2)

Surface area = 2(2x/2 + 1/4)

Surface area = 2(x + 1/4)

Surface area = 2x + 2/4

Surface area = 2x + 1/2 sq. ft
