What are the possible solutions to the equation: x-12 = sqrt x+44

Ainat [17]

possible solutions for equation $x-12 = \sqrt{x+44}$ is $x=5 , x=20$

<u>Step-by-step explanation:</u>

Here we have to find the possible solutions to the equation: x-12 = sqrt x+44 .Let's find out:

⇒ $x-12 = \sqrt{x+44}$

⇒ $(x-12)^2 = (\sqrt{x+44})^2$

⇒ $(x^2+144-24x) =x+44$

⇒ $(x^2+144-24x) -(x+44) =0$

⇒ $(x^2+100-25x) =0$

⇒ $x^2-25x+100 =0$

⇒ $x^2-20x-5x+100 =0$

⇒ $x(x-20-5(x-20) =0$

⇒ $(x-5)(x-20)=0$

⇒ $x-5=0 , x-20=0\\$

⇒ $x=5 , x=20$

Therefore , possible solutions for equation $x-12 = \sqrt{x+44}$ is $x=5 , x=20$

LaTanya says that the growth factor of f(x) = 100(1.25) is 25%. What mistake did LaTanya make?

vladimir2022 [97]

Answer:

The first error consists in the multiplication of f (x) = 100 * (1.25), the value she mentions is incorrect since it is 125.

It would be a 125% increase really.

In order for LaTanya's phrase to have no error she had to mention that it was a 25% increase over the original amount, in this way, the phrase would make sense and be valid.
