Solution:
<u>Note that:</u>
- Given expression: (x² + 4x) − (x² + 6x − 3)
<u>Remove the brackets</u>
- (x² + 4x) − (x² + 6x − 3)
- => x² + 4x - x² - 6x + 3
<u>Combine like terms</u>
- x²(1 - 1) + x(4 - 6) + 3
- => x²(0) + x(-2) + 3
- => -2x + 3
Body surface area = the square root of product of the weight in kg times the height in cm divided by 3600.

Answer:
18ft^2
Step-by-step explanation:
I'm going to use a dilation method to help solve this.
First we need to find your base. So 12/4 = 3.
6*3 = 18.
18 ft^2
Well if her speed is 55 miles per hour
1 hour= 55 miles
? hour= 192 miles
You can divide by 55 and get
3.5 ( I rounded the number)
Hope this helps?
