Answer:
3x2(4x – 3) + 1(4x – 3)
Step-by-step explanation:
Answer with explanation:
Relation between Speed , Distance and time
Distance =Speed × Time
→It means Speed is inversely Proportional to time.
As distance will remain constant , in that frame of reference
If speed of light in a Medium

Then, time taken to cross the medium = t seconds or hours or another unit of time.
Now, If speed of light is 50% of the speed of light relative to us
That is Speed of light in another medium

Then, time taken to cross the medium = 2t seconds or hours or another unit of time.
Using Unitary Method

Answer:
36 minutes
Step-by-step explanation:
Depth of the fjord = 1308 m
Rate at which the submersible dives = 35 meters/minute
Distance to the bottom of the fjord should be 48 m
Distance the submersible has to go underwater is 
Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

The time taken by the submersible to dive the required distance is 36 minutes.
Answer:
<h2>a) x = 16 and y = 6</h2><h2>b) P = 864 in</h2>
Step-by-step explanation:
a)
The opposite sides of the rectangle are of equal length.
