Step 4-5 is where Andrew made an error. Since 9.8 is positive, -11.8 + 9.8 = -2. He subtracted 9.8 from 11.8 instead of adding it.
Hope this helps! Message me or comment under this post if you need further assistance!
Answer:
√9 × √6
√54
√27 × √2
Step-by-step explanation:
We can obtain the answer to the question given above as illustrated below:
3√6
Recall
a√b = √(a×a×b)
Thus,
3√6 = √(3×3×6)
3√6 = √(9 × 6)
Recall
√(a × b) = √a × √b
√(9 × 6) = √9 × √6
Therefore,
3√6 = √9 × √6
Recall
√9 × √6 = √(9 × 6)
√9 × √6 = √54
Thus,
3√6 = √54
Recall
√54 = √(27 × 2)
√54 = √27 × √2
Therefore,
3√6 = √27 × √2
Therefore,
3√6 = √9 × √6 = √54 = √27 × √2

Answer:
Step-by-step explanation:
two points on it are (-1,0) and (0,1)
slope= (1-0)/(0-(-1))=1/1=1
eq of line is y-0=1(x+1)
y=x+1
let y>x+1
put x=0,y=0
0>0+1
or 0>1
which is false .
Hence y<x+1
or x+1>y
or x-y+1>0
