From the question, we need to expand the given equation;
[tex]8(9j\text{ + 5 + 5y)}[/tex]to expand the equation, we will have to multiply the term outside the bracket by each term inside the bracket.
Which means we will multiply 8 by each of 9j, 5 and 5y.
[tex]8(9j\text{ + 5 + 5y) = 8(9j) + 8(5) + 8(5y)}[/tex]
