Answer:
387
Step-by-step explanation:
To evaluate 3 - 6( Z - 2) ^3 at Z = -2, replace Z with -2:
3 - 6( -2 - 2) ^3
Simplify this result, obtaining 3 - 6( -4) ^3.
According to order of operations rules, exponentiation must be done first here, before multiplication and before subtraction. Therefore:
3 - 6( -4) ^3 → 3 - 6( -64). Again, these rules require that we multiply before subtracting:
3 - 6( -64) = 3 + 384, or 387
Answer:-523/52
Step-by-step explanation:
If he maintained a steady speed, he would drive 3 kilometers far after 3 hours.
<h3>What is steady speed?</h3>
Uniform or steady speed refers to a body's motion in a given direction without acceleration.
Since steady speed means a constant speed in changing time intervals, we would consider he speed as 1 km/h.
Time for which he is maintaining the steady speed is 3 h.
We know by the formula, Distance = Speed × Time
Therefore, putting the values given we get
Distance = 1 × 3 kilometers
Hence, distance travelled by he after 3 hours of maintaining steady speed is 3 kilometers.

The answer for this is Substitution property
Substitution Property is considered as one of the most intuitive of the mathematical properties that you'll probably encounter. You may have been using substitution without even knowing it. This property says that if x=y, then in any true equation involving y, you can replace y with x, and yet you'll still have a true equation.
Take a look at the attached example shown below.
