Answer:
Option A. 4, 4.5, 5, 5.5
Step-by-step explanation:
Left point: a=x=4
Right point: b=x=6
Range: r=b-a→r=6-4→r=2
Width of each of the four equal intervals: w=2/4→w=0.5
The first left endpoint is x1=a→x1=4
The second left endpoint is x2=x1+w→x2=4+0.5→x2=4.5
The third left endpoint is x3=x2+w→x3=4.5+0.5→x3=5
The fourth left endpoint is x4=x3+w→x4=5+0.5→x4=5.5
Then, the list is: x1, x2, x3, x4 = 4, 4.5, 5, 5.5

Chuck that in calculator and evaluate
Answer:
Option B) -9 is correct
The evaluated given expression when x=-3 is 2x+x=-9
Step-by-step explanation:
Given expression is 2x+x
Now to evalute the given expression when x=-3 as below :
2x+x when x=-3
That is put x=-3 in the given expression we get
2x+x=2(-3)+(-3)
=-6-3
=-9 ( adding the like terms here )
Therefore 2x+x=-9
The evaluated given expression when x=-3 is 2x+x=-9
Option B) -9 is correct
