So it would be                                                  7 (x - 8) = 42
divide by 7 on both sides                              ______    ___
                                                                              7            7
                                                                            (x - 8) =   6
                                                                               +8   = +8
                                                                                 x    =  14 cm

Given length l=7
         width w=x-8
          area=42
area=wl
42=7(x-8)
42=7x-56
7x=98
x=98/7
x=14

15% 40% as whole numbers
Alex17521 [72]

Answer: Not possible

Step-by-step explanation: A whole number is an integer or a number without fractions. Both 15% and 40% are less than 1 since they are less than 100%; therefore, it is impossible to express them as whole numbers. They can only be expressed as the mixed numbers of 0.15 and 0.4, or 15/100 and 40/100.
