Answer:
you want us to do all that
Step-by-step explanation:
Answer:
21 kilometers
Step-by-step explanation:
Let the height be 
. Then, the length of the base is 
. The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to 
, which is in turn equal to 441. Since must be positive, then 
, meaning that the height is 
kilometers.
Answer:
a - b = 12
Step-by-step explanation:
Given
= 12 ← factor the numerator
a² - b² ← is a difference of squares and factors as
a² - b² = (a - b)(a + b)
Thus
= 12
Cancel the common factor (a + b) on numerator/ denominator, thus
a - b = 12
The answer is 8/36 , multiply both numerator and denominator by 4
In order to find out the association, you need to plot the data. Given that m is x, and n is y, after plotting, the graph shows a positive linear association. The graph rises from left to right. So the answer is letter D.
