Explanation:
Right now, we are given:
.
is basically b divided by -8. In order to solve for b, we need to "undo" the division part - and to do so, we use the opposite of division, which is multiplication.
So, we would multiply both sides by -8: 
On the left, when we multiply by -8, the -8 we multiplied and the -8 in the denominator cancel out, so we're just left with b. On the right side, it's simply the multiplication of -2 by -8. Here, since we have two negative numbers, the negatives cancel out to become a positive product, and 2 * 8 = 16. So, -2 * -8 = 16.
As you did not want the answer, I will not say explicitly the actual answer, but hopefully you can figure it out from my explanation above!
Answer:
<h2>x = 3</h2>
Step-by-step explanation:

Step-by-step explanation:
Initial velocity(u) = 60 km/hr = 50/3 m/s
final velocity(v)= 0 (stops at rest)
acceleration(a) = -0.05 m/s²
display (s)=?
v²-u²=2as
0²- (50/3)= 2(-0.05)s
2500/9= 0.1s
s= 25000/9 m
ANSWER

EXPLANATION
We use the method of completing the squares.
The equation is

We rewrite the above equation to obtain;

We divide through by 3 to obtain;

We add half the coefficient of

to both sides of the equation to get,

The right hand side is now a perfect square.

We now take square root of both sides to get;

We add -2 to both sides,

We simplify to obtain,
