Answer:
or 
Step-by-step explanation:
Given:
We are to find the values of 
such that these two functions are equal.
Substitute 
.
We get 
Hence for we have the functions to be equal.
Now for 
We see the functions are once again equal.
At constant acceleration the equation is
v = u + at where u = initial speed, a = acceleration. t = time and v = final speed
So here we have 18 = 0 + 7t
t = 18/7 = 2.6 seconds ( to nearest tenth)
Volumn = LWH
small rectangle = 5 x 5 x 12 = 300 sq yds
Larger rectangle = 4 x 12 x 18 = 864 sq yds
