45x = 42�60
x = 42�60 / 45
x = 14*4 = 56 km/hr
x = 42�60 / 45
x = 14*4 = 56 km/hr

Answer:
- g(x) = 6|x + 1| - 2
-----------------------------------------
Given:
- Function f(x) = 2|x + 3| - 2
Find a function g which is a horizontal shrink by a factor of 1/3 of f(x).
Horizontal shrink by a factor of k is:
- g(x) = f(x/k)
Apply this to the given function:
- g(x) = f(x : 1/3) = f(3x) = 2|3x + 3| - 2 = 6|x + 1| - 2
the width of Yun's area model is 7x units or ( x-2 )units .
<u>Step-by-step explanation:</u>
Here we have , Yun was trying to factor 7x^2-14x. He found that the greatest common factor of these terms was 7x and made an area model: What is the width of Yun's area model. Let's find out:
We know that area of rectangle :
⇒ .........(1)
Now , According to question we have
⇒
⇒
Comparing this equation to equation (1) we get that :
⇒ or ,
Therefore , the width of Yun's area model is 7x units or ( x-2 )units .
