Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
First what you should do for this case is to rewrite the expression carefully to find the correct answer.
You must respect the properties of the roots.
Group the terms correctly.

C. Simple interest at 3 percent
Step-by-step explanation:
<span>If Marvin has 4 books to read, this means we have to divide 4 by 2/3 (the amount of each book that he is currently reading in a night), which equals 4/1×3/2=twelve halves, 12/2÷2/2=6/1=6. Hopefully that answered the question succinctly for you.</span>
