Which of the following equations demonstrate that the set of polynomials is
not closed under the certain operations?
A. Multiplication: 3x4 + x°)(-2x4 + x) = -6x8 + x?
+ to
B. Division: (x2 + 2x) = (x + 1) = x+
х
x +1
C. Multiplication: (x2 + 2x)(x + 1) = x+3x2+2x
D. Addition: 3x4 + x°) + (-2x+ + x) = x4 + 2x3

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60

hope this is the answer you're looking for: )

umm you say your want to . but you do know that this is the mathematics.  

o~o

im super bad at school but u for some reason need to have points to ask questions and you get points by answering so thats all im doing sorry for t r o l l i n g
