F(x) = 2x^3 + 5x^2 -6x-7 g(x) = 2x-3 find (f - g) (x)
AlexFokin [52]

Given:

The function are:

f(x)=2x^3+5x^2-6x-7

g(x)=2x-3

To find:

The function (f-g)(x).

Solution:

We have,

f(x)=2x^3+5x^2-6x-7

g(x)=2x-3

We need find (f-g)(x).

(f-g)(x)=f(x)-g(x)

(f-g)(x)=2x^3+5x^2-6x-7-(2x-3)

(f-g)(x)=2x^3+5x^2-6x-7-2x+3

On combining like terms, we get

(f-g)(x)=2x^3+5x^2+(-6x-2x)+(-7+3)

(f-g)(x)=2x^3+5x^2-8x-4

Therefore, the correct option is B.

a box is a cuboid with dimensions 28cm by 15 cm by 20 cm all measured to the nearest centimetre. Disc cases are cuboids which me
nataly862011 [7]

Answer:

See Below

Step-by-step explanation:

To get volume of cuboid, we multiply the 3 dimensions.

<u>Volume of Box</u> = 28 * 15 * 20 = 8400

<u>Volume of 1 disc case</u> = 1.5 * 14.2 * 19 = 404.7

<u>Volume of 17 disc cases</u> = 17 * 404.7 = 6879.9

Since, volume of 17 disc cases is less than volume of the cuboid box, definitely 17 disc cases will fit the box.
