Answer:

S8 = 112

Step-by-step explanation:.​

The question is incomplete

Assuming we are given the following

First term a =7

number of terms n = 8.

Common difference d=2

We can find the sum of the first 8terms S8

Substitute the given values

S8 = 8/2[2(7)+(8-1)(2)]

S8 =4(14+7(2))

S8=4(14+14)

S8 = 4(28)

S8 = 112

Hence the sum of the first 8terms is 112

Note that the values are assumed values

Answer:B

Step-by-step explanation:

Using what is known as the "Triangle Inequality Theorem" a+b can not be less than c or else it is not a triangle. (A and B are the smallest sides of the triangle).

A) 6cm + 15cm = 21cm which is less than 23cm: Not a triangle

B) 5cm + 9cm  = 14cm which is greater than 13cm: This makes a triangle and therefore the answer is B

C) 5cm + 8cm = 13cm which is less than 13cm: Not a triangle
