The standard form of the quadratic equation is given by:
ax ^ 2 + bx + c
What we must do in this case is to rewrite the given equation.
We have then:
2/3 (x-4) (x + 5) = 1
(x-4) (x + 5) = 3/2
(x ^ 2 + 5x-4x-20) = 3/2
2x ^ 2 + 2x-40 = 3
2x ^ 2 + 2x-43 = 0
Thus, the values of a, b and c are:
a = 2
b = 2
c = -43
Answer:
a = 2
b = 2
c = -43
Set up the Pythagorean theorem.
The ladder is the hypotenuse
The wall is the length of the triangle
Pythagorean theorem states: a^2 + b^2 = c^2
Thus. 16^2 + b^2 = 12^2
Solve for b and that will be your answer for the question.
