sp2606 [1]
Volume of a cone = 1/3 π r² h 

235.5 = 1/3 (3.14) r² (9) 

(3.14) r² (9)  = 706.5

r² = 25

r = 5

Which equations are correct? Select each correct answer. −5a4(2a2+4)=−10a6−20a4 −4x2(2x2+5)=−8x4−20x2 −6y4(4y2+2)=−24y8−12y4 −4b

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.
