If we take both sides of the equation \frac{1}{3} x=5 and <em>multiply either expression by 3</em>, the equality becomes

3\cdot\frac{1}{3}x=3\cdot5\\x=15

Multiplication of both sides of an equality by the same number keeps the equality true, and we call this property the multiplication property of equality.

Can anyone help me please?
miss Akunina [59]

Answer:

  5. -18x^3y^4 +54x^2y^4

  6. 6x^2 -40x +50

Step-by-step explanation:

Use the distributive property. The factor outside parentheses multiplies each term inside parentheses.

__

<h3>5.</h3>

  (9xy)(-2x^2y^3+6xy)=(9xy)(-2x^2y^3)+(9xy)(6xy^3)\\\\=\boxed{-18x^3y^4+54x^2y^4}

__

<h3>6.</h3>

  (3x-5)(2x-10)=3x(2x-10)-5(2x-10)\\\\=6x^2-30x-10x+50=\boxed{6x^2-40x+50}
