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

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
