$9x^3+30x^2+24x \\ \\ gcf = 3x \\ \\ 3x ( \frac{9x^3}{3x} + \frac{30x^2}{3x} + \frac{24x}{3x} ) \\ \\ 3x(3x^2 + 10x + 8) \\ \\ 3x ( 3x^2 + 6x + 4x + 8) \\ \\ 3x(3x(x + 2) + 4(x + 2)) \\ \\ 3x(x + 2)(3x + 4) \\ \\$

The final result is: 3x(x + 2)(3x + 4).

Use function notation to write the equation of the line

blondinia [14]

$f(x)=mx+b\to y=mx+b$

We have two points:

$(-3,\ 0);\ (-4,\ 7)$

The point slope form of the line:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute

$m=\dfrac{7-0}{-4-(-3)}=\dfrac{7}{-1}=-7$

$y-0=-7(x-(-3))\\\\y=-7(x+3)\\\\y=-7x-21$

Answer:

$f(x)=-7x-21$

Use the formula S A = 6s2 , where S A is the surface and s is the edge length of the cube , to solve his problem.

Gennadij [26K]

To find the surface area of the cube using the formula, you would substitute in 2 1/2 for the length of the side.

SA = 6 x 2.5 x 2.5
SA = 37.5 ft.²

You are finding the area of one face (2.5 x 2.5) and multiplying it by six because there are six groups of this.
