|4x + 4| = 15

First, let's get rid of the absolute value signs to get the first solution.

4x + 4 = 15

Subtract 4 from both sides

4x = 11

Divide each side by 4

x = 11/4 or 2.75

Now, let's get the solution by changing 15 to -15.

4x + 4 = -15

Subtract 4 from both sides

4x = -19

Divide both sides by 4

x = -19/4 or -4.75

Answer: 544 cm²

Step-by-step explanation:

There are 5 sections to the tent:

Front (triangle): A = $\frac{1}{2}$ · b · h
Back (triangle): same dimensions as Front
Base (rectangle): A = L · w
Left Side (Rectangle): A = L · w
Right side (rectangle): same dimensions as Left Side

Total Surface Area = Front & Back + Base + Sides

= 2[ $\frac{1}{2}$ (12 · 8)] + (12 · 14) + 2(14 · 10)

= 96 + 168 + 280

= 544

1. Find diagonal.

d = 2r

d = 2(9)

d = 18

2. Find length of square.

each length of square = x

$x : 18 = 1 : \sqrt{2}$

$\frac{x}{18} = \frac{1}{\sqrt{2} }$

$\sqrt{2}x = 18$

$x = \frac{18}{\sqrt{2} } = 9\sqrt{2}$

3. Find area of circle and square.

Area for circle

$A = \pi r^2$

$A = \pi (9)^2$

$A = 81\pi = 254.4690...$

Area for square

$A = (length)^2$

$A = (9\sqrt{2})^2$

$A = 162$

4. Subtract area of circle to area of square.

254.4690... - 162 = 92.4690...

5. Find the shaded region.

92.4690... / 4 = 23.1172...

Rounded to the nearest hundredth = 23.12

Sauron [17]

Answer:

(f ο g)(-1) = 1

Step-by-step explanation:

Given

$f(x) = \frac{8}{x+2}$

$g(x) = 4 x^{2} +2$

f ο g)(-1) = f(g(-1) = f(4(-1)² + 2)

= f(6)

= $\frac{8}{x+2}$

= $\frac{8}{6+2}$

= 1

Final answer:-

(f ο g)(-1) = 1
