If a rectangle has a height of (3x-5) and base (x+10)cm and area equal to 98sqcm , find its dimension
------
Equation:
base*height = area
------
(3x-5)(x+10) = 98 cm^2
----
3x^2 +25x - 50 = 98
----
3x^2 + 25x -148 = 0
---
Factor:
(x-4)(3x+37) = 0
----
Dimensions:
3x-5 = 3*4-5 = 7cm
x+10 = 14 cm
================
