Answer:

f(x) and g(x) are closed under subtraction because when subtracted, the result will be a polynomial.

Step-by-step explanation:

$f(x)-g(x)\\=(a_0+a_1x+a_2x^2...+a_nx^n)-(b_0+b_1x+b_2x^2...b_mx^m)$

Assume m>=n WOLOG

$=(a_0-b_0)+(a_1x-b_1x)+(a_2x^2-b_2x^2)+...+(a_nx^n-b_nx^n)-b_{(n+1)}x^{n+1}-...-b_{m-1}x^{m-1}-b_mx^m$

$=(a_0-b_0)+(a_1-b_1)x+(a_2-b_2)x^2+...+(a_n-b_n)x^n-b_{(n+1)}x^{n+1}-...-b_{m-1}x^{m-1}-b_mx^m$

Are also a polynomial in general, but maybe in a different degree

Closure under subtraction means, for all polynomials, under the operation of subtraction, it also belongs to polynomials

Given that AXB is complementary to both CYD and FZE, and mAXB = 36°, what is mCYD + mFZE?

anyanavicka [17]

Complementary angles always equal 90°
So here is how to find what mCYD + mFZE equal
mCYD + mFZE + mAXB
mCYD + mFZE + 36° = 90°
Subtract
mCYD + mFZE = 54°

stepladder [879]

-- 'Truncated' to one decimal place, it's 9.9 ,

-- 'Rounded' to one decimal place, it's 9.9 .

(These two operations don't always produce the same result.)
