1. Consider the expression $-5a^4(2a^2+4)=-10a^6-20a^4.$

Start with left side and use dustributive property :

$-5a^4(2a^2+4)=-5a^4\cdot 2a^2-5a^4\cdot 4=-10a^6-20a^4.$

This option is true.

2. Consider the expression $-4x^2(2x^2+5)=-8x^4-20x^2.$

Start with left side and use dustributive property :

$-4x^2(2x^2+5)=-4x^2\cdot 2x^2-4x^2\cdot 5=-8x^4-20x^2.$

This option is true.

3. Consider the expression $-6y^4(4y^2+2)=-24y^8-12y^4.$

Start with left side and use dustributive property :

$-6y^4(4y^2+2)=-6y^4\cdot 4y^2-6y^4\cdot 2=-24y^6-12y^4\neq -24y^8-12y^4.$

This option is false.

4. Consider the expression $-4b^3(5b^2+3)=-20b^6-12b^3.$

Start with left side and use dustributive property :

$-4b^3(5b^2+3)=-4b^3\cdot 5b^2-4b^3\cdot 3=-20b^5-12b^3\neq -20b^6-12b^3.$

This option is false.

Answer: A, B - true, C, D - false.
