Answer:

[tex]-4(16-18)[/tex], [tex][16 + (-18)](-4)[/tex]

Step-by-step explanation:

Given: The low temperature on Monday was 16°F. The low temperature on Tuesday was 18°F cooler. The low temperature on Wednesday was –4 times Tuesday’s temperature.

To find: expression that can be used to describe the low temperature on Wednesday

Solution:

Temperature on Monday = 16°F

So,

Temperature on Tuesday = [tex](16-18)\°F[/tex]

Temperature on Wednesday = [tex]-4(16-18)\°F[/tex]

So, expression [tex]-4(16-18)=(16-18)(-4)[/tex] can be used to describe the low temperature on Wednesday.

Also,

[tex](16-18)(-4)=[16 + (-18)](-4)\,\,\left \{\because (a-b)=\left [ a+(-b) \right ] \right \}[/tex]

So, expression [tex][16 + (-18)](-4)[/tex] also represent temperature on Wednesday.

Answer:

(16 – 18)(–4)

[16 + (–18)](–4)
