Answer:

Step-by-step explanation:

Area of the rectangle = length * width

                                   = 10 * 5

                                   = 50 m²

Area of the smaller rectangle that is white color = 7 * 2

                                                                               = 14 m²

Triangle:

base = b = 5 m

Height = h = 16 - 10 = 6 m

Area of triangle = \frac{1}{2}*b*h\\

                          = \frac{1}{2}*5*6\\\\= 5*3\\\\= 15 m^{2}

Area of shaded area = area of bigger rectangle - area of smaller rectangle + area of triangle

 = 50 - 14  + 15

= 21 m²

Answer:

214\frac{2}{3}

Step-by-step explanation:

8\bigg(\frac{81}{3}+\frac{241}{3}\bigg)\frac{1}{4} \\\\= 8\bigg(\frac{81+241}{3}\bigg)\frac{1}{4} \\\\= 8\bigg(\frac{322}{3}\bigg)\frac{1}{4} \\\\= 8\times\frac{322}{3}\times\frac{1}{4} \\\\= 2\times\frac{322}{3}} \\\\= \frac{644}{3}} \\\\= 214\frac{2}{3} \\

Select the correct answer.
mariarad [96]

Answer:

B.

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
