<PRE><B>Question 189382</B>
If the area of a triangle is 40 cm^2 and the base equals (2h + 6), what is the height? 
-----------------------
A=(1/2)bh 
---
bh = 2A
h = (2A)/b
--------------------
h = (2*40)/(2h+6)
---
Cross-multiply to get:
2h^2 + 6h - 80 = 0
h^2 +3h - 40 = 0
(h+8)(h-5) = 0
Positive solution:
h = 5 cm
======================
