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

summing both sets we have one set: (1,6]
so
a) represent our set
b) also represent because all numbers between 4-6 and 6 are in our set
c)also represent, all numbers are in main set
d)also represent
Answer: 5x + (x + 54) = 6x + 54
So now 6x + 54 = 90 because u are solving a right angle.
90 - 54 is 36. So 6x = 36 and 36 divided by 6 is 6. Your answer for X = 6 Hope this helps you please mark brainliest

I answer and then give me brainliest. sorry I am being rude
:/
I think it's B because it contains the highest numbers
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.
