Answer:
Reason given in step 2. is incorrect. It should read; "Distributive Property."
Step-by-step explanation:
The reason given to go from :

Is that 6 square root 1 x 5
It would be D:7
It needs to have one side bigger than
Answer:
Step-by-step explanation:
2x+2≤x+4≤3x+4
means : 2x+2≤x+4 ...(1) and x+4≤3x+4
(1) : 2x-x≤4-2 so : x≤2....(*)
(2) :3x+4 ≥x+4 .... 3x-x ≥ 0 so: x≥0 ....(**)
by (*) and (**) : 0≤x≤2 so : A=0 and B = 2
