into the expresion
:

Now, you must evaluate:

2) You have to substitute the given value of "x" into the second expression:

Finally, evaluating, you get the following result:

3) According to the Zero exponent Rule, any non-zero number with an exponent of zero is equal to 1.
Then, substituting
into the expression
and then evaluating, you get:

The ball has Kinetic energy because it's in motion.
They amount to 168 legs.
Each spider has 8 legs; 8(8) = 64
Each cockroach has 6 legs; 5(6) = 30
Each bee has 6 legs; 7(6) = 42
Each deer has 4 legs; 3(4) = 12
Each cow has 4 legs; 4(4) = 16
The antlered creature will have 4 legs; 1(4) = 4
Adding all of these together,
64+30+42+12+16+4 = 168
