Answer 1

Respuesta:

5a + 7a + a = 13a

- 5a + 2a -  4a = -3a

x.x +$3x^{2}$ = $4x^{2}$

x + x + 3(x + 2 ) - 5x = 2x + 3x + 6 -5x = 6

$3xy^{2} +7 x^{2}y - 3y^{2} x$ = $7x^{2} y$

- (- 3x +  4 ) - (3x - 8 ) = 3x - 4 -3x + 8= 4

(-5)(-2)(-3) + (-3)(5)(-4) = -30 + 60 = 90

x.x.x + $x^{2}$ . x + $7x^{3}$ = $x^{3}$ + $x^{3}$ +$7x^{3}$ =$9x^{3}$

4xy de 8xy + 4 = - 4xy + 4

5xy +  8 - 4xy + 8 = xy + 16
