Does anyone know how he got from step 1 to step 2??????????

padilas [110]

9514 1404 393

Explanation:

Both sides of the equation are squared.

$\dfrac{x-12}{4}=\sqrt{x} \qquad\text{given}\\\\ \left(\dfrac{x-12}{4}\right)^2=x \qquad\text{square both sides}\\\\ \left(\dfrac{x}{4}-3\right)^2=x \qquad\text{divide out the fraction}\\\\ \dfrac{x^2}{4^2}-\dfrac{6}{4}x+9=x \qquad\text{$(a-b)^2=a^2-2ab+b^2$}\\\\\dfrac{x^2}{16}-\dfrac{5x}{2}+9=0 \qquad\text{subtract $x$}$

I like this better without fractions, so would multiply by 16 at this point (or earlier).

x^2 -40x +144 = 0

(x -36)(x -4) = 0

x = 4 or 36 . . . . . . x = 4 is extraneous

The solution is x = 36.

31.24 to 1 decimal place

Blababa [14]

Answer:

31.2

Step-by-step explanation:

Because you only round up if the number next to the 1st decimal place is greater than 5, you just drop the 4 and keep 31.2.
