Which equation can be rewritten as x + 4 = x2? Assume x greater-than 0 StartRoot x EndRoot + 2 = x StartRoot x + 2 EndRoot = x S

Mila [183]

We have been given an equation $x+4=x^2$ . We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.

Since x is greater than, so we will take positive root on both sides of our given equation as:

$\sqrt{x+4}=\sqrt{x^2}$

$\sqrt{x+4}=x$

Upon looking at our given choices, we can see that option C is same as our answer.

Therefore, option C is the correct choice.

horrorfan [7]

To prime factorization would be A: 2 X 3 X 5 X 7

Because if your do 2 X 3 it would be 6

Then you do 5 X 7 it would be 35

And 6 X 35 would be 210

AND THAT IS FACTORING THE PROBLEM
