$445$

$"express 89 as "89=(90-1)$

$rArr5(90-1)$

$=450-5$

$=445$

See a solution process below:

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:

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

$400 + 45 =>$

$445$
