A=xy+yz
A=y*(x+z)
y=A/(x+z)
Answer:
A = 30 unit^2
Step-by-step explanation:
To find the area of the triangle
A = 1/2 b*h where b is the length of the base and h is the height
b = 12 and h =5
A = 1/2 (12*5)
A = 1/2 *60
A = 30 unit^2
The correct answer is -6m-n+3. You have to simplify the expression.
