Answer:
D. N = w² + 8w + 12
Step-by-step explanation:
The current size is w by w+4, so the area is ...
A = w(w+4)
When each dimension is increased by 2, the new size is (w+2) by (w+4+2). The latter dimension can be simplified to (w+6). Now, the new area is ...
N = (w+2)(w+6) = w² +8w +12 . . . . . . . matches choice D
Answer:
1) No
2) Yes
Step-by-step explanation:
Given : If it took Carlos 30 minutes to cycle from his house to the library yesterday.
To find : Was the distance that he cycled greater than 6 miles?
Solution :
The relation between speed , distance and time is
1) The average speed at which Carlos cycled from his house to the library yesterday was greater than 16 feet per second.
Speed = 16 feet per second
Converting into miles,
Time = 30 minute
Converting into seconds,
The distance he covered is
No, the distance that he cycled is not greater than 6 miles.
2) The average speed at which Carlos cycled from his house to the library yesterday was less than 18 feet per second.
Speed = 18 feet per second
Converting into miles,
Time = 30 minute
Converting into seconds,
The distance he covered is
Yes, the distance that he cycled is greater than 6 miles.
