Which of the following intervals represents the set (1,4) u [2,6]?
fenix001 [56]
Set is a sum of two intervals :(1,4) u [2,6] 
In the first interval it is open on both sides so 1 and 4 don't belong to this interval, the second is closed so both 2 and 6 belong to interval and numbers between 2 and 6
We can write it as 1<x\leq 6
summing both sets we have one set: (1,6]

Please help thank you very much

Answer:

96

lower right

Step-by-step explanation:

Part 1

Givens

a1 = - 20

d = +4

n = 30

Equation

a30 = a1 + (n - 1)d

Solution

a30 = -20 + (30 - 1)*4

a30 = -20 + 29*4

a30 = - 20 + 116

a30 = 96

=====================

Part 2

Formula

Sum = (a1 + L)*n/2

n = 30

So only the two on the right can be considered

a1 = -20

L = 96

Sum = (-20 + 96)30/2 is the bottom right. D if you think of it that way.
