Answer:

4 $x^{4}$ - 4x³ + 20x² - 20x

Step-by-step explanation:

(g × f)(x) = g(x) × f(x) = (x³ + 5x)(4x - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x³(4x - 4) + 5x(4x - 4) ← distribute both parenthesis

= 4 $x^{4}$ - 4x³ + 20x² - 20x

This can also be done using FOIL, that is

(x³ + 5x)(4x - 4)

= 4 $x^{4}$ - 4x³ + 20x² - 20x

Nathan bought a cd for his friend. The length and width of the cd case is 4 18⁄25 inches. What is the area of the cd case?

ale4655 [162]

Answer:

Hence the area of CD bought by Nathan is 22.2784 square inches.

Step-by-step explanation:

The length and width of a CD bought by Nathan is $4\frac{18}{25}=\dfrac{118}{25}$ inches.

As CD have the same length and width this means it will be of the shape of a square.

Hence, the area of CD is given by:

Area of CD=length×width

= $4\dfrac{18}{25}\times4\dfrac{18}{25}$

= $\dfrac{118}{25}\times\dfrac{118}{25}$

= $\dfrac{118\times118}{25\times25}$

= $\dfrac{13924}{625}$

= $22.2784$

Hence the area of CD bought by Nathan is 22.2784 square inches.

The area of the base (six triangles with a base 15m and a height 7.5√3m):

$A_B=6\cdot\dfrac{1}{2}\cdot15\cdot7.5\sqrt3\approx585\ m^2$

The area of side walls (six triangles with a base 15m and a height 12m)

$A_W=6\cdot\dfrac{1}{2}\cdot15\cdot12=540\ m^2$

The surface area:

$A_B+A_W=585+540=1,125\ m^2$
