Answer:
Zero.
Step-by-step explanation:
Anything times zero is zero.
[tex]5c \cdot d^2 \cdot 0=0[/tex]
Since you have something, as in [tex]5c \cdot d^2[/tex], times 0, then the result is 0 regardless of the value of the something part I mentioned.
Needless work.
See that c=-2 and d=2.
So 5c=5(-2)=-10 and [tex]d^2=d(d)=2(2)=4[/tex]
Plugging them in gives:
[tex]5c \cdot d^2 \cdot 0[/tex]
[tex]-10 \cdot 4 \cdot 0[/tex]
[tex]-40 \cdot 0=0[/tex]
