Step-by-step explanation:
0.89 = 1 - 1/(k²)
Start by subtracting 1 from both sides:
0.89 - 1 = -1/(k²)
-0.11 = -1/(k²)
Multiply both sides by -1:
0.11 = 1/(k²)
Multiply both sides by k²:
0.11 k² = 1
Divide both sides by 0.11:
k² = 1 / 0.11
Take the square root:
k = √(1 / 0.11)
Correct: m,b,c
incorrect: a,n,c

If you would like to find the inequality that shows the number of books Hugh can sell to meet his goal, you can do this using the following steps:
x = ? ... the number of books
$8 * x >= $400
8 * x >= 400
x >= 400 / 8
x >= 50 books
The correct result would be: <span>$8 * x >= $400.</span>
Answer:
The expression is not factorable
