The given expression is
[tex] \frac{7}{2}h-3(5h- \frac{1}{2}) [/tex]
First we have to distribute -3 on 5h and -1/2
That is,
[tex] =\frac{7}{2}h-15h+ \frac{3}{2} [/tex]
Now we have to combine the like terms, that is
[tex] = \frac{7h-30h}{2} + \frac{3}{2} = - \frac{23h}{2} + \frac{3}{2} [/tex]
So out of the given four options, correct option is A .
