As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.
Where 
represents base (hypotenuse) and 
as height of the triangle.
We know that:
Using this data we fill the formula.
Hope this helps.

Answer:
27m^6n^12
Step-by-step explanation:
(3)^3 = 27
m^2^3 = m^6
n^4^3 = n^12
Answer:
4+(-6)+8+(-1)
Step-by-step explanation:
if she starts at 4 points and her first turn she cuts 6 trees then you can add a negative 6 which is the same as subtracting that 6 when she plants 8 add those points then for her last turn add a negative 1 which is the same as subtracting 1 and she should end up with 5 points.
No they do not form a right triangle
Let x be the number of racing bikes, and let y be the number of mountain bikes.
1) 140x + 110y = 26150
2) 180x + 120y = 31800
Solve for one of the variables and plug that in to the other equation:
From equation 1: 140x = 26150 - 110y
x = (26150-110y)/140
Plug this into equation 2:
180((26150-110y)/140) = 31800
Solve for y, and find that y = 85 (the number of mountain bikes).
Plug that y into either equation to find x:
140x + 110(85) = 26150
x = 120 (the number of racing bikes).
So the answer is: 120 racing bikes and 85 mountain bikes.
