We need to substitute the given values into the expression, that is
[tex]-5(-3-10)[/tex]the term into the parenthesis is equal to -3-10=-13, then our last expression is equivalent to
[tex]-5(-13)[/tex]By making the product and taking into account the law of signs (minus times minus equal plus), we have
[tex]-5(-13)=65[/tex]Then, What is the value of x(y-10)? answer: 65
