Answer:
The area of the triangle is 48 in².
Step-by-step explanation:
A right triangle is a triangle formed when to legs come together to make a 90° angle. The 'legs' of the triangle can also be called referred to the base and the height of the triangle. The general formula for the area of a triangle is:
A = 
b*h, where b = base and h = height
In this case, the leg measures are given as 8 inches and 12 inches, so we can put these values into our formula to solve for area:
A = (8)(12) = 48
Answer:
Step-by-step explanation:
hello :
1) the system is : y=5x+4
y = 2x+1
so :5x+4 =2x+1
5x-2x=1-4
3x= -3 so : x= -1 but y =2x+1 put x=-1 you have : y =-1
the solution : (x,y) =( -1, -1)
2) the system is : x + y = 4
4x -y = 1
means : y = - x+4 (line red)
y= 4x-1 (line blue)
graficly : intrsection is : (x,y) =(1 ,3 )
