Answer:

Step-by-step explanation:

Calculate the derivative of the function:

Calculate the zeros of the derivative:

Let's check the derivative sign:

Sketch a parabola open down
(before the brackets there is the number -3 < 0)
Look at the picture.
Where the derivative is negative, the function decreases.
Where the derivative is positive, the function increases.
Therefore your answer is:

No, 3(20)+5=65 and 20+95=115.
65 is not equal to 115; therefore they are not parallel because they are not congruent.
Sorry i dont really understand this
Answer:
624 square inches of cardboard were used to make the box.
Step-by-step explanation:
Slant height of the box = l = 20 inches
Side of the base of the box = s = 12 inch
Area of the base = 
Area of triangular face = 
There are 4 triangle faces, and single square base , so the total area is :



624 square inches of cardboard were used to make the box.
Total rooms =200
So inequality is given by
