Answer:
x = 6.3
Step-by-step explanation:
since the quadrilaterals are similar then the ratios of corresponding sides are in proportion, that is
=
( substitute values )
=
( cross- multiply )
4x = 7 × 3.6 = 35.2 ( divide both sides by 4 )
x = 6.3
Answer:
B.
f(x) and g(x) are closed under subtraction because when subtracted, the result will be a polynomial.
Step-by-step explanation:
Assume m>=n WOLOG
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
