Subtract these polynomials. (4x2 – X+6) - (x2 + 3) =
O A. 482 - 2x+3
O B. 5x2 - x + 9
O c. 3x2 – X+3
O D. 4x2 - 2x + 9

dont say C just becuase its chosen, i didnt mean to

C

Step-by-step explanation:

(4x^2-x+6)-(x^2+3)

First, you can change the second polynomial to make it an addition problem.

(4x^2-x+6)+(-x^2-3)

Then you add them together so 4x^2-x^2=3x^2

-x has nothing to subtract or add so we bring it down

and 6-3=3 making the answer

3x^2-x+3

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

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
