which of the following equations demonstrate that the set of polynomials is
not closed under the certain operations?
o a. division: (x2 –5x+3)=(x-2) = x-3+ -32
o
o
o
b. subtraction: 3x4 + x? ) - (-2x4 + x) = 5x4
c. multiplication: (x2 - 5x+3)(x - 5) = x2 - 10x2 +28x - 15
d. addition: (x2 + x) + (x + 1) = x2 + 2x+ 1

the answer is 8.64

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
