Answer:

Step-by-step explanation:

To evaluate f(g(x)) substitute x = g(x) into f(x)

f(g(x))

= f(x²)

= 2(x²) - 4 = 2x² - 4

Ill give you braindeath if you get this right

Answer:

The larger angle is 144 degrees and the smaller angle is 36 degrees

Step-by-step explanation:

Because this is a supplementary angle you have to find out what x is to solve this equation $2.4x+9.6x=180$

Because 2.4x and 9.6x are like terms we add them $2.4x+9.6x=12x$

So now to find x we divide 180 by 12 to get 15 $\frac{12x}{12} =\frac{180}{12}$

We replace the x with 15 $2.4(15)+9.6(15)=36+144$

We add 36 and 144 which equals 180

Find mZPQR. help asap

DENIUS [597]

<h3>Answer: D) 72</h3>

======================================

Work Shown:

Angle PQR = (far arc - near arc)/2

2x+72 = ( (2x+252) - (2x+108) )/2

2x+72 = 144/2

2x+72 = 72

2x = 72-72

2x = 0

x = 0/2

x = 0

-------------

Angle PQR = 2x+72

Angle PQR = 2(0)+72

Angle PQR = 72 degrees
