$445$

#### Explanation:

$\text{express 89 as } 89 = \left(90 - 1\right)$

$\Rightarrow 5 \left(90 - 1\right)$

$= 450 - 5$

$= 445$

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:

$5 \times \left(80 + 9\right)$ or $5 \left(80 + 9\right)$

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

$\left(5 \times 80\right) + \left(5 \times 9\right) \implies$

$400 + 45 \implies$

$445$
