Question

Si a=6, b=7.5 y c= -2, calcula:
ab + c =

2a + 3b =

a + 2b + 3c =

ac =

a² + b² =
a² + c² =

ab + bc =

Answer 1

Respuesta:

ab + c =6.7,5-2

=45-2

=43

2a + 3b =2.6+3.7,5

=12+22.5

=34,5

a + 2b + 3c =6+2.7,5+3.-2

=6+15-6

=15

ac =6.-2

=-12

a² + b² =6²+7,5²

=36+56,25

=92,25

a² + c² =6²+(-2)²

=36-4

=32

ab + bc =6.7,5+7,5.-2

=45-15

=30
