A because 21 is a greater number than 9 and therefore should be in the denominator. That leaves you with 9 which is a smaller number and should go on the numerator. Hope this helped you!

Answer:

a. 40

Step-by-step explanation:

Given

$g(x)=2x$ and $h(x)=x^2+4$

$(h\circ g)(x)=h(g(x))$

$(h\circ g)(x)=h(2x)$

We plug in 2x into $h(x)=x^2+4$ .

$(h\circ g)(x)=(2x)^2+4$

$(h\circ g)(x)=4x^2+4$

We now substitute x=-3.

$(h\circ g)(-3)=4(-3)^2+4$

$(h\circ g)(-3)=36+4=40$

The correct choice is A.

1. Harsha makes a scale drawing of a window. She uses the scale 1cm represents 20cm.

guajiro [1.7K]

Part (A)

(1 cm)/(20 cm) = (6 cm)/(x cm)

1/20 = 6/x

1*x = 20*6

x = 120

120 cm = 120/100 = 1.2 m

<h3>Answer: 1.2 m</h3>

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

Part (B)

2.2 m = 2.2*100 = 220 cm

(1 cm)/(20 cm) = (x cm)/(220 cm)

1/20 = x/220

1*220 = 20*x

20x = 220

x = 220/20

x = 11

<h3>Answer: 11 cm</h3>
