Which of the following shows the polynomial below written in descending order?
3x3 - 5x + x + 9 + 4x11
A. 9 + 4x11 + x + 3x3 - 5x
B. 4x11 + x? - 5x + 9 + 3x3
C. 4x11 + x + 3x3 – 5x + 9
D. X? + 3x3 + 9 + 4x11 - 5x

the answer is a.

135 and 80

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
