Answer:

Step-by-step explanation:

Dilation. Since it's only the size of the figure that's changing

Height of the smaller one: 4

Width of the smaller one: 6

Height of the bigger one: 6

Width of the bigger one: 9

6/4 = 1.5

9/6 = 1.5

Since both 6/4 and 9/6 was 1.5, that means that the Width and Height was proportional and that the two trapezoids is at a ratio o:

1 : 1.5

One unit of the smaller one is 1.5 units on the bigger one.

Scilla [17]

Step-by-step explanation:

Put the values of x to W(x).

$W(x)=\dfrac{80(2x+15)}{x+6}\\\\\\x=0\to W(0)=\dfrac{80(2(0)+15)}{0+6}=\dfrac{80(0+15)}{6}=\dfrac{80(15)}{6}=\dfrac{1200}{6}=200\\\\x=1\to W(1)=\dfrac{80(2(1)+15)}{1+6}=\dfrac{80(2+15)}{7}=\dfrac{80(17)}{7}=\dfrac{1360}{7}=194\dfrac{2}{7}\\\\x=4\to W(4)=\dfrac{80(2(4)+15)}{4+6}=\dfrac{80(20+15)}{10}=8(35)=280\\\\x=12\to W(12)=\dfrac{80(2(12)+15)}{12+6}=\dfrac{80(24+15)}{18}=\dfrac{80(39)}{18}=\dfrac{3120}{18}=173\dfrac{1}{3}\\\\x=24\to W(24)=\dfrac{80(2(24)+15)}{24+6}=\dfrac{80(48+15)}{30}=\dfrac{80(63)}{30}=\dfrac{5040}{30}=168$
