Question

stiind ca 2x +2y +45=59 Determinati 4xy+4xx+32.

Answer 1

2x + 2y + 45 = 59
2x + 2 y = 59 - 45
2 ( x + y ) = 14
x + y = 14 : 2
x + y = 7
sunt mai multe solutii
x = 1 , y = 6
4 x 1 x 6 + 4 x 1 x 1 + 32 = 24 + 4 + 32 = 60
x = 2 , y = 5
4 x 2 x 5 + 4 x 2 x 2 + 32 = 40 + 16 + 32 = 88
x = 3 , y = 4
4 x 3 x 4 + 4 x 3 x 3 + 32 = 48 + 36 + 32 = 116
