Question

If x= 5 and y = 2, find the values of: (1) (xy + y) (2) (x + yy) - 1 ​

Answer 1

Step-by-step explanation:

=(1)(5×2+2)(2)(2+5×5)-1

=(1)(10+2)(2)(5+4)-1

=12(2)9-1

=24×8

=192

well I am not sure but I went through your question..

Answer 2

Answer:

215

Step-by-step explanation:

Put the value of x and y

Put the value of x and y( xy + y) (2) (x+yy) -1

Put the value of x and y( xy + y) (2) (x+yy) -1x = 5, y = 2

Put the value of x and y( xy + y) (2) (x+yy) -1x = 5, y = 2(5*2 + 2) (2) ( 5+ 2*2) -1

Put the value of x and y( xy + y) (2) (x+yy) -1x = 5, y = 2(5*2 + 2) (2) ( 5+ 2*2) -1 (10+2) * 2 *(5 +4) -1

Put the value of x and y( xy + y) (2) (x+yy) -1x = 5, y = 2(5*2 + 2) (2) ( 5+ 2*2) -1 (10+2) * 2 *(5 +4) -1(12*2*9) -1

Put the value of x and y( xy + y) (2) (x+yy) -1x = 5, y = 2(5*2 + 2) (2) ( 5+ 2*2) -1 (10+2) * 2 *(5 +4) -1(12*2*9) -1(24*9) -1

Put the value of x and y( xy + y) (2) (x+yy) -1x = 5, y = 2(5*2 + 2) (2) ( 5+ 2*2) -1 (10+2) * 2 *(5 +4) -1(12*2*9) -1(24*9) -1216 -1= 215 ans
