Given the equation: x^2-12=-15 By using the equation editor or uploading a picture, rewrite the equation in the form:
(x-h)^2=k

Given :-

To Find :-

Solution :-

The given equation to us is ,

x² - 12x = -15

Now for completing the square ,

x² -2(6)(x) = -15

x² - 2(6)(x) + 6² = 6² - 15

(x -6)² = 6² - 15

(x -6)² = 36 -15

(x - 6)² = 21

Hence the required answer is (x-6)² = 21.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
