<PRE><B>Question 472839</B>
Find the expression in terms of x for the area of the triangle
Area=1/2 b h Base= 5x^3/7 Height= 4/x 
:
A = {{{1/2}}}*{{{(5x^3)/7}}}*{{{4/x}}}
:
Multiply the numerators, and denominators
A = {{{(20x^3)/(14x)}}}
:
We can reduce the fraction by dividing top and bottom by 2x
A(x) = {{{(10x^2)/7}}}, area in terms of x</PRE>
