Answer:

See a solution process below:

Explanation:

We can rewrite the number 89 as:

#89 = 80 + 9#

We then rewrite the expression in the problem as:

#5 xx (80 + 9)# or #5(80 + 9)#

Using the distributive property we can rewrite and evaluate the expression as:

#(5 xx 80) + (5 xx 9) =>#

#400 + 45 =>#

#445#
