Answer:
Step-by-step explanation:
we know that
The area of the right triangle ABC is equal to

we have



substitute the values





The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
therefore
The solution is
6 divided by 3 = 2
1 apple = 2 dollars
2 x 12 = 24 dollars
