PART A
Volume = Area of a triangle base x height (..or length)
Volume = 2,400cm^3
Volume = 1/2(16)(h)(20)
2,400cm^3=1/2(16)(h)(20)
2/400cm^3/160 = 160(h)/160
Part A= 15cm^3=height of the box
PART B
Surface Area = 1/2(15*16)(2)+20(17)(2)+16(20)
Surface Area = 240+680+320
Surface Area = 1,240
Part B = You will need approximately 1,240cm of cardboard.

Answer:
T(a) =(a+2)/11
Step-by-step explanation:
The inverse of the inverse is the function
To find the inverse let T^-1(a) be y
y = 11a -2
Exchange y and a
a = 11y -2
Solve for y
Add 2 to each side
a+2 = 11y -2 +2
a+2 =11y
Divide each side by 11
(a+2)/11 =y
T(a) =(a+2)/11
