A = 6 t - 8

A = 6 * - 3 - 8 = - 18 - 8 = - 26

B = - 3 x + 7

B = - 3 * - 2 + 7 = 6 + 7 = 13

C = - 3 y² - 8 y - 5

  = - 3 ( - 3 )² - 8 * ( - 3 ) - 5

  = - 3 *9 + 24 - 5

  = - 27 + 24 - 5

  = - 8

Bonjour;

A= 6*-3 -8

= -12 -8

= -20

B= -3*-2 +7

= 6+7

= 13

C= -3(-3)² -8*-3 -5

= -3 *9 +24 -5

= -27 +24 -5

= -8
