Answer 1

Answer:

>Here we Have (a+m) ² -(a-m) ²

->we have equation for(a+m)² = a² + 2am + m²

->we have equation for(a-m)² = a² - 2am + m²

->so we can use it and we write below step

->(a² + 2am + m² )-( a² - 2am + m² )

->after open the braces we got,

->a² + 2am + m² - a² +2am - m²

->2am+2am =4am

->so based on above simplification answer is 4am

Answer 2

Answer:

Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches. (Cubic inches can also be written in3.)
