It is false! Not every cylinder is a prisem.
Answer:
50
Step-by-step explanation:
When n = 6, the length is 3 * 6 + 2 = 20 and the width is 6 - 1 = 5. We know that the perimeter of the rectangle is twice the sum of its length and width. The sum of the length and width is 20 + 5 = 25 and twice that is 25 * 2 = 50.
Let x represent the days it will take for the stalk to be at least 300 cm tall
3x+9≥300
3x≥291
x≥97
