Answer:

3(x)^3 + 2(x)^2 + 22x - 15

Step-by-step explanation:

(3(x)^2 + 2x - 3) (x + 5)

=>(3(x)^2 + 2x - 3) (x) + (3(x)^2 + 2x - 3) (5)

=>3(x)^3 + 2(x)^2 - 3x + 15x + 10x - 15

=>3(x)^3 + 2(x)^2 + 22x - 15

Math<br> Asi<br> What is the greatest common factor of 64 and 72?
Advocard [28]

Answer: 8

Step-by-step explanation:

We can use prime factor method , that is we will express each of the number as a product of their prime factor

64 =  2x2x2x2x2x2

72 = 2x2x2x3x3

Greatest common factor is therefore:

2 x 2 x 2= 8

Which equation is the inverse of f(x)=LaTeX: \frac{1}{x+2}1 x + 2 A. LaTeX: f^{-1}\left(x\right)=\frac{1}{x}+2f − 1 ( x ) = 1 x
inna [77]

Answer:

g^{-1}x = \frac{1-2x}{x}

Step-by-step explanation:

Given the function g(x)= \frac{1}{x+2}, we are to find the inverse of the function and this can be done y following the simple steps:

Step 1: Replace y with g(x)

g(x)= \frac{1}{x+2}\\y= \frac{1}{x+2}

Step 2: Interchange x with y

x= \frac{1}{y+2}

Step 3: Make y the subject of the formula;

x= \frac{1}{y+2}\\y+2 = \frac{1}{x}\\y =  \frac{1}{x} - 2\\Find \ the\ LCM\\y = \frac{1-2x}{x}

Step 4: Replace y as g^{-1}(x)

g^{-1}x = \frac{1-2x}{x}

Hence the inverse of the function is g^{-1}x = \frac{1-2x}{x}
