Question

Evaluate the expression for x = 5, y = 3, and z = 14 .

Answer 1

5 times 5 is 25 and 6 times 3 is 18 and 20 times 14 is 280 so

25-18=7    7+280=287  

287

4 times 3 is 12  12 times 14 is 168

so i think its 287

                   --------

                      168

sorry if i got it wrong
