Step-by-step explanation:
we have

where
d expresses a car's distance in feet
t is the number of seconds
<em>Find the distance d for t=8 sec</em>

<em>Find the distance d for t=8.2 sec</em>

The total distance in this interval of 0.2 sec is

<em>Find the speed of the car</em>
Divide the total distance by the time

therefore
The truck travel must to have a constant speed of 
Answer:
4
Step-by-step explanation:
Its four because:
4 x 3 = 12
12 + 4 = 16
4 x 4 = 16
Four times times three plus four is like saying four times four.
+ √6 = √9
The first step is to get
by itself. We can do this by subtracting
from each side, and simplifying 
= 3 - 
Now we square both sides
5x = (3 -
)²
Using the formula (a - b)² = a² -2ab + b², (3 -
)² = 15 - 6
5x = 15 - 6
x =
