Answer:
Step-by-step explanation:
Given
Solving (a): Write as inverse function
Represent a(d) as y
Swap positions of d and y
Make y the subject
Replace y with a'(d)
Prove that a(d) and a'(d) are inverse functions
and
To do this, we prove that:
Solving for 
Substitute 
for d in
Solving for: 
Substitute 5d - 3 for d in
Add fractions
Hence:
Every triangle’s inner angles’ addition equals to 180°
So if we find the x:
38°+x+2°+x=180°
40°+2x=180°
2x=180°-40°=140°
x=140°/2
x=70°
Now if we find the I hope this helped :)
To find the volume, you cube the edges.
So make it easier, you can cube the numerator and then the denominator.
2*2=4*2=8
3*3=9*3=27
8/27
You cannot simplify it any more.
The volume of the container is 8/27 feet cubes.
You could add the whole number parts first then add the fractions. Finally add the 2 results.
