A= l*w
168= 14*w
Divide both sides by 14
168/14= 14w/14
12=w
Final answer: 12 ft (I'm not sure if you meant to switch the order of b and c).
Answer:

Step-by-step explanation:
.
We can round 58697 to 59000, and 3664 to 4000. The computation becomes

The actual result is 55033, so it's quite a good result
She did not simplify under the square root correctly.
<h3>Quadratic equation</h3>
Given the quadratic expression
5x^2 - 6x - 8 = 0
Using the general formula, we will have:

From the given equation;
a = 5
b -6
c = -8
Substitute the values into the formula to have:

From the given solution, we can see that she did not simplify under the square root correctly.
