Answer:
d. x = -3
Step-by-step explanation:
<u />÷ (x+8)(x-2) = 0
f(x) / g(x) = 0
Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).
<u /> = 0 ------ square both sides
x + 3 = 0
solve for x:
x = -3
What you have to do is multiply 21 by 2. it is 42. $42 dollars was the original price of the bookcase.
