ANSWER
[tex](25\times9)+(75\times9)=9(25+75)[/tex]
[tex](25\times9)+(75\times9)=9(100)[/tex]
[tex](25\times9)+(75\times9)=900[/tex]
EXPLANATION
According to the distributive property,
[tex](a\times b)+(a\times c)=a(b+c)[/tex]
This implies that,
[tex](25\times9)+(75\times9)=9(25+75)[/tex]
[tex](25\times9)+(75\times9)=9(100)[/tex]
The Right Hand Side of the equation now has 2 factors.
We solve now to obtain;
[tex](25\times9)+(75\times9)=900[/tex]
