Answer:

-9x^{9} y^{5}

Step-by-step explanation:

(-8x⁴y³)(2x⁵y²)+7x⁹y⁵  (grouping like terms)

= (-8)(2) (x⁴x⁵) (y³y²) +7x^{9} y^{5}

= -16 x^{4+5} y^{3+2 } + 7x^{9} y^{5}

= -16 x^{9} y^{5} + 7x^{9} y^{5}

= (-16 + 7)x^{9} y^{5}

= -9x^{9} y^{5}

Which property justifies this question -5 x 12 = 12 x -5
cluponka [151]

Answer:

Commutative Property of Multiplication

Step-by-step explanation:

Commutative Property of Multiplication is the switching of the order first factor  (multiplicand) and the second factor (multiplier), which does not change the product. For example, 4 × 5 = 5 × 4

-5 × 12 = -60

12 × -5 = -60
