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 $x=5 , x=20$

700 miles the train takes 5 hours to a travel the distance at what unit rate is the train traveling?

dalvyx [7]

Answer:

The rate is 140 miles per hour

Step-by-step explanation:

We can use the formula distance is equal to rate times time

The distance is 700 miles and the time is 5 hours

D =rt

700 = r*5

Divide each side by 5

700/5 = 5r/5

140 =r

The rate is 140 miles per hour

In my opinion there are an infinite amount of answers though what i got when i solver wasn’t right i would think you just have to try and solve on your own.
