Answer 2

Answer:

-67.2

Step-by-step explanation:

Simplify the given expression (−3.5)(−3)(−6.4)

WE apply PEMDAS rule to simplify it

Lets start with parenthesis part

We multiply first two parenthesis

(−3.5)(−3)

Negative and negative becomes positive

(−3.5)(−3) is 10.5

Now we multiply it with -6.4. Positive times negative is negative.

$10.5 \cdot (-6.4)= -67.2$

$(-3.5)(-3)(-6.4)=-67.2$
