I’m not sure I only answer these for the points :)
Answer:
8
Step-by-step explanation:
Absolute value of 6 is 6. Absolute value of -2 is 2. 6+2 is 8.
Answer:
1) x=8, y=138
2) x=110
Step-by-step explanation:
If the dimensions are "nice" factors of the quadratic, and if y > -3, we have
.. area = (y +3)(y +5)
y+5 is greater than y +3, so we take the width to be ....
.. width = y+3
The average speed would be 600 km/hr.
Step-by-step explanation:
Let the original speed be 'x'
Let the decreased speed be 'x-200'
Distance = 600 km
Time increased by 30 minutes
According to question, it becomes,

So, The average speed would be 600 km/hr.
