First plug in g(x) into f(x)

F((g(x))=2(2x+3)

And now you plug in -8

F(g(-8))=2(-16+3)

F(g(-8))=2(-13)

F(g(-8))=-26

anygoal [31]

ANSWER

$(4 - \pi) {ft}^{2}$

EXPLANATION

The area of the square is

${l}^{2}$

The length of the square is

$l = 2ft$

The area of the square is

$= {2}^{2} = 4 {ft}^{2}$

Area of the circle is

$= \pi \: {r}^{2}$

The radius of the circle is

$r = \frac{2}{2} = 1ft$

Area of circle is

$= \pi \: \times {1}^{2} = \pi {ft}^{2}$

The area of the shaded region is

$= (4 - \pi) {ft}^{2}$

Answer:

$\frac{-117}{10}$

Step-by-step explanation:

1) Change the mixed fractions into improper fractions:

$-3\frac{1}{5} + (-8\frac{1}{2} )\\= \frac{-16}{5} - \frac{17}{2}$

2) Multiply the first fraction by 2/2 and the second fraction by 5/5 in order to create common factors on the denominator (You can do this because you are essentially multiplying by one, for example 2/2 = 1):

$\frac{-16}{5} *\frac{2}{2} - \frac{-17}{2} * \frac{5}{5} \\ =\frac{-32}{10} - \frac{85}{10}$

3) Simplify the numerator(top part) while keeping the denominator(bottom part) the same:

$\frac{-32}{10} -\frac{85}{10} \\\\=\frac{-32 - 85}{10}\\ \\= \frac{-117}{10}$
