Answer:

It is proved that f(x)g(x)=|x|=|x-4|-4.

Step-by-step explanation:

Given functions are,

f(x)=|x|

g9x)=|x-4|-4

To show,

f(x)g(x)=|x|=|x-4|-4

Consider,

(fg)(x)=f(g(x))=f(|x-4|-4)=||x-4|-4|

now if,

x>4\implies x-4>0 then (fg)(x)=||x-4|-4|=|x-4|-4

x then (fg)(x)=||x-4|-4|=||-(x+4)|-4|=|x+4-4|=|x|

Hence the reslt.

solmaris [256]

Answer:

Pual needs 3 gallons

Step-by-step explanation:

∵ The dimensions of the four walls are:

   25 × 8 , 30 × 8 , 25 × 8 , 30 × 8

∴ The area of painting = 2(25 × 8) + 2(30 × 8)

                                     = 400 + 480 = 880 square feet

∵ each gallon paint 400 square feet

∴ The number of gallons = 880/400 = 2.2, so he needs 3 gallons

Can someone help me with this Geometry question ASAP, thanks!
slega [8]

We are given an isosceles triangle.

An isosceles triangle has corresponding angles of corresponding sides same.

<em>Therefore, other angle is also of (3x+7) degrees.</em>

(5x+13) and (3x+7) makes a linear pair.

Therefore,

(5x+13) + (3x+7)  = 180

5x +13 + 3x +7 = 180.

8x +20 = 180.

Subtracting 20 from both sides, we get

8x +20-20 = 180-20.

8x = 160

Dividing both sides by 8, we get

<h3>x = 20.</h3><h3>Therefore, correct option is 3rd option. </h3>
