if 3x/4 - 13 = -9 then what is the value of x^2


If 3x4 13 9 Then What Is The Value Of X2 class=

Sagot :

Answer:

x² = [tex]\frac{256}{9}[/tex]

Step-by-step explanation:

[tex]\frac{3x}{4}[/tex] - 13 = - 9 ( add 13 to both sides )

[tex]\frac{3x}{4}[/tex] = 4 ( multiply both sides by 4 to clear the fraction )

3x = 16 ( divide both sides by 3 )

x = [tex]\frac{16}{3}[/tex]

Then

x² = ( [tex]\frac{16}{3}[/tex] )² = [tex]\frac{16^2}{3^2}[/tex] = [tex]\frac{256}{9}[/tex]
