Answer:
(0, 7]
Step-by-step explanation:
Let's call the width W and the length L. The length is 18 feet more than the width, so:
L = W + 18
The area can be no more than 175, so:
A ≤ 175
LW ≤ 175
Since L = W + 18:
(W + 18) W ≤ 175
W² + 18W ≤ 175
W² + 18W - 175 ≤ 0
(W - 7) (W + 25) ≤ 0
-25 ≤ W ≤ 7
However, the width of the table can't be nonpositive, so:
0 < W ≤ 7
Or in interval notation, (0, 7].
Answer:
420 meters
Step-by-step explanation:
to find volume for a rectangular shape you need to do length×Width×Height
In this problem the...
Length=20
Width=12
and depth which is same as height=1.75
To find the volume you just have to do 20×12×1.75

Answer:
4 hours 55 minutes
Step-by-step explanation:
Time, speed, and distance are related by ...
t = d/s
t = (177 mi)/(36 mi/h) = 4 33/36 h = 4 11/12 h
The fractional part of this time is ...
11/12 hour is (11/12)(60) = 55 minutes
The van will take 4 hours and 55 minutes to travel a distance of 177 miles.
When I factored it I got 4a^2(8a+3)
