Add 1/4 to both sides to get T=-2/4
Step-by-step explanation:
after 60% reduction he paid 40% of its price=224

224×100=40×?
?=560
In a rectangular triangle
.
We have 
Therefore opposite = 3uints and adjacent = 4units.

We need the length of hypotenuse.
Use the Pythagorean theorem:

Substitute:

(12z^2 + 25z + 12)/(3z^2 - 2z - 8)
You have to factor it. You know how to factor it right?
(12z^2 + 16z + 9z + 12)/(3z^2 - 6z + 4z - 8)
(4z(3z + 4) + 3(3z + 4))/(3z(z - 2) + 4(z - 2))
((4z + 3)(3z + 4))/((3z + 4)(z - 2))
(4z + 3)/(z - 2)
