Complete the statement: If 8 = m/4 then m - 12 = ?. Explain.

andre [41]

Solve for m:
8 = m/4

8 = m/4 is equivalent to m/4 = 8:
m/4 = 8

Multiply both sides of m/4 = 8 by 4:
(4 m)/4 = 4×8

(4 m)/4 = 4/4×m = m:
m = 4×8

4×8 = 32:
Answer: m = 32 thus m - 12 = 32 -12 = 20

How many extraneous solutions does the equation below have? StartFraction 9 Over n squared 1 EndFraction = StartFraction n 3 Ove

BigorU [14]

The equation has one extraneous solution which is n ≈ 2.38450287.

Given that,

The equation;

$\dfrac{9}{n^2+1} =\dfrac{n+3}{4}$

We have to find,

How many extraneous solutions does the equation?

According to the question,

An extraneous solution is a solution value of the variable in the equations, that is found by solving the given equation algebraically but it is not a solution of the given equation.

To solve the equation cross multiplication process is applied following all the steps given below.

$\rm \dfrac{9}{n^2+1} =\dfrac{n+3}{4}\\\\9 (4) = (n+3) (n^2+1)\\\\36 = n(n^2+1) + 3 (n^2+1)\\\\36 = n^3+ n + 3n^2+3\\\\n^3+ n + 3n^2+3 - 36=0\\\\n^3+ 3n^2+n -33=0\\$
