What is the solution of x = 2 + startroot x minus 2 endroot?
x = 2
x = 3
x = 2 or x = 3
no solution

x = 2 or x = 3

Step-by-step explanation:

we have the expression:

First we must remove the square root, for this we pass the 2 to the left:

and we move the square root to the left as an exponent of two:

We develop the square binomial:

and clear the right side for the equation to be equal to zero:

combining like terms:

Because it is a quadratic equation we will have two answers, which we can find by the general formula or by factoring:

To factor we open two parenthesis, both with an x, and look for two numbers that when multiplied result in +6 and when added result in -5, those numbers are -2 and -3, so the factoring is:

And now we use the Zero Product Property, whic is if two thing are multiplied and result in zero one of the two or both things must zero, in this case:

and

the solutions are: x = 2 or x = 3; both satisfy the equation.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
