PLEASE HELP ME! Which of the following equations demonstrate that the set of polynomials is not closed under the certain operations?
A. Multiplication: (x² + 2x)(x + 1) = x2 + 3x + 2x
+
B. Multiplication: (3x4 + x)(-2x4 + x) = -6x8 + x + x
+
X
C. Division: (x2 +
+2x)+(x + 1) = x+
X +1
O D. Addition: 6x4 + x®)+(-2x* + x) =
+2x3

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
