Question

porfavor ayúdeme enserio urgente!!!!!!!!!​

Answer 1

Explicación paso a paso:

1.

P x Q = { (1;a) , (1;b) , (1;c) , (2;a) , (2;b) , (2;c) , (3;a) , (3;b) , (3;c) , (4;a) , (4;b) , (4;c) }

2.

A x B = { (x;4) , (x;5) , (x;6) , (y;4) , (y;5) , (y;6) , (z;4) , (z;5) , (z;6) }

3.

A x B = { (5;7) , (5;8) , (6;7) , (6;8) , (7;7) , (7;8) }

Entonces:

a = 7

b = 8

c = 6

Hallar: a + b + c = 7 + 8 + 6 = 21

4.

A = (2.m ; 19)

B = (10 ; 3.n+1)

Como:

A = B

2.m = 10 19 = 3.n + 1

m = 10/5 19 - 1 = 3.n

m = 2 18 = 3.n

m = 2 6 = n

Hallar: m + n = 2 + 6 = 8
