We have the formula for the area of a triangle equal to A=l*w, where stands for the area, l for the length and w for the width. Given in the problem are the following:
A=135 m
l=6+w
w=w
Solving for the value of w, we have:
A=(w+6)*w
135=w²+6w
w=9 meters
Therefore, the length of the rectangle is 15 meters.

Answer:
53.33mph
Step-by-step explanation:
Let's calculated the total time spent on the journey first;
For the first 300miles the time spent is ;
From Distance = speed× time
time = Distance/ speed
= 300/60 = 5 hours
Similarly for the last 100mile the time taken is ;
100/40 = 2.5 hours
Total time spent = 5 +2.5 = 7.5 hours
Total distance covered 400miles
Therefore average speed = 400/7.5 =53.33mph
The value of b in the equation 5/2b+(-25/2) is 1.
Answer:
C
Step-by-step explanation:
- choose any 2 sets of corresponding values and use the formula
( y2 - y1 ) / ( x2 - x1 )
you'll get -3/4
