Answer:

Step-by-step explanation:
Area of parallelogram =base x height
Area=20 x 8=160
Units=

The maximum value can be determined by taking the derivative of the function.
(dh/dt) [h(t)] = h'(x) = -9.8t + 6
Set h'(x) = 0 to find the critical point
-9.8t + 6 = 0
-9.8t = -6
t = 6/9.8
Plug the time back into the function to find the height.
h(6/9.8) = -4.9(6/9.8)^2 + 6(6/9.8) + .6
= 2.4
And I don't understand your second question.
Answer:
no solution
Step-by-step explanation:
2 x 2x, 2 x -2, you now have 4x=4x-4, subtract 4x and 4x and you are left with -4
