Which equation represents y = x2 − 10x + 30 in vertex form?
riadik2000 [5.3K]

To complete the square, you can add (and subtract) the square of half the x coefficient.

... y = x² -10x + 30

... y = (x² -10x +25) + (30 -25)

... y = (x -5)² +5

1. Find the value of x. If your answer is not an integer, leave it in simplest radical form.
adelina 88 [10]

Answer:

4\sqrt{73} units

Step-by-step explanation:

The given shape is a right triangle and in right triangles the sum of square length of legs is equal to square length of hypotenuse (represented with x in here):

12^2 + 32^2 = x^2

1168 = x^2 find the root for both sides

4\sqrt{73} =x
