Answer:
<u>The width of the rectangle is 6 cm and its length is 9 cm</u>
Step-by-step explanation:
Length of the rectangle = 3 cm greater than its width
Perimeter of the rectangle = 30 cm
Find the dimensions of the rectangle.
x = Width of the rectangle
x + 3 = Length of the rectangle
Now, let's solve for x, using the perimeter formula this way:
2 * width + 2 * length = Perimeter of the rectangle
Replacing with the values and variables we have:
2 * x + 2 * (x + 3) = 30
2x + 2x + 6 = 30
4x = 30 - 6
4x = 24
x = 6 ⇒ x + 3 = 9
<u>The width of the rectangle is 6 cm and its length is 9 cm</u>
Answer:
![3.7691\times 10^{7}\\9.8762\times 10^{6}](https://tex.z-dn.net/?f=3.7691%5Ctimes%2010%5E%7B7%7D%5C%5C9.8762%5Ctimes%2010%5E%7B6%7D)
Step-by-step explanation:
Since the question doesn't give the number of people in each city with driving license, then we can assume all people don't have the required driving license. Therefore, it means the question just wants us to convert the given numbers into scientific notation. The numbers are therefore
![3.7691\times 10^{7}\\9.8762\times 10^{6}](https://tex.z-dn.net/?f=3.7691%5Ctimes%2010%5E%7B7%7D%5C%5C9.8762%5Ctimes%2010%5E%7B6%7D)
