Answer:
24 inches represents 9 miles in the map
Step-by-step explanation:
To solve this problem you take into account that 8 inches represents 3 miles and that x represent the number of inches for 9 miles. That is:
8 ------- 3
x ------- 9
This is simply a rule of three, then you calculate:
![x=\frac{8\ x\ 9}{3}=\frac{72}{3}=24](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B8%5C%20x%5C%209%7D%7B3%7D%3D%5Cfrac%7B72%7D%7B3%7D%3D24)
Hence, 24 inches represents 9 miles in the map
Answer:
g(x+2) means that x + 2 is going into g(x).
Step-by-step explanation:
Given:
g(x) = x^2 - x
g(x + 2)
g(x+2) means that x + 2 is going into g(x)
x = x + 2
Substitute:
g(x + 2) = (x + 2)^2 - (x + 2)
Solve:
g(x + 2) = (x + 2)^2 - (x + 2)
= x^2 + 4x + 4 - (x + 2)
= x^2 + 4x + 4 - x - 2
Simplify:
g(x + 2) = x^2 + 3x + 2
Perimeter = 2( Length + Width)
<em>Given that Perimeter = 3 1/12 feet and Width = 2/3 foot, plug the values into the formula to find the length:</em>
3 1/12 = 2( Length + 2/3)
3 1/12 = 2Length + 4/3
2 Length = 3 1/12 - 4/3
2 Length = 7/4
Length = 7/4 ÷ 2
Length = 7/4 x 1/2
Length = 7/8
<em>Now that we know the length is 7/8 and the width is 2/3, find the area:</em>
Area = Length x Width
Area = (7/8)(2/3) = 7/12
Answer: Area = 7/12 ft²
