The means of simplifiying is by factoring

Given the expression

(2x - 9) (x+ 6)

Expand

(2x - 9) (x+ 6)

2x² +12x -9x - 54
2x² + 3x - 54

Hence the simplified form of the expression is 2x² + 3x - 54

The option A is showing the domain ans the range of the function F(x) as inverse of F(x).

In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]{\displaystyle f^{-1}.}[/tex]

Here in the graph we can see that the option A has the clear range of the function.

[tex]2------- > 1\\4------- > 2\\6------- > 3\\8------- > 4[/tex]

Hence the option A is showing the domain ans the range of the function F(x) as inverse of F(x).

Step-by-step explanation:

When the remainder of the polynomial is 0, it is a factor and when it is not zero, then it is not a factor.

A polynomial is an algebraic equation with at least the power of its  being 2.

When the power of the variable is 2, it is called a quadratic equation.

Analysis:

If [tex]x^{3}[/tex] + 4[tex]x^{2}[/tex] -12x + 24 is divided by x -3,  quotient is [tex]x^{2}[/tex]

remainder 7[tex]x^{2}[/tex]-12x+24

7[tex]x^{2}[/tex]-12x+24 divided by x-3, quotient is 7x, remainder 10x + 24

10x+24 divided by x-3, quotient is 10, remainder is 54

In conclusion, since it has a non zero remainder, then x - 3 is not a factor of the polynomial.

This is the form of a circle. Use this form to determine the center and radius of the circle.

(x−h)2+(y−k)2=r2

Match the values in this circle to those of the standard form. The variable r

represents the radius of the circle, h represents the x-offset from the origin, and k

represents the y-offset from origin.

r=3

h=2

k=1

The center of the circle is found at (h,k)

Step-by-step explanation:

25% more is found by adding 25% of the original value to the original value. It is equivalent to multiplying the original value by (1 +25%) = 1.25.

__

25% of Roberto's yield is ...

  147.4 kg × 0.25 = 36.85 kg

If Roberto's yield increases by that amount, it will be ...

  147.4 kg + 36.85 kg = 184.25 kg

Roberto should expect a yield of 184.25 kg.

Answer:

c = 14.43 units to the nearest hundredth.

Step-by-step explanation:

We are given 2 sides and the included angle so we use the Cosine Rule.

c^2 = a^2 + b^2 - 2absinC

      = 20^2 + 17^2 - 2.29.17cos45

      = 208.17

   c = √208.167

      =  14.43.
