Simplify the following expression.
5 [13 + 10 = (3 + 2)] + 9 x 2

5 [13 + 10 = (3 + 2)] + 9 x 2

     5(23)     +      5      +  9*2  

         155   + 5     +9*2

                160  +     18

                        178

the answer is 178    

Have a nice day :)

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
