Step-by-step explanation:

y = y

x - 2 = 2x - 3 - 3x²

3x² + x - 2x = - 3 + 2

3x² - x = - 1

a = 3, b = -1, c = 0

$\sf{x = \frac{-b \pm \sqrt{b^{2} - 4ac} }{2a} }$

$\sf{x = \frac{- (-1) \pm \sqrt{-1^{2} - 4 (0)} }{2(3)} }$

$\sf{x = \frac{ 1 \pm \sqrt{1 - 0} }{6} }$

$\sf{x = \frac{ 1 \pm \sqrt{1} }{6} }$

$\sf{x = \frac{ 1 + 1 }{6} }$

$\sf{x = \frac{ 2 }{6} }$

$\sf{x = \frac{ 1 }{3} }$

Substitution :

y = x - 2

y = ⅓ - 2

y = ⅓ - 6/3

y = - 5/3

y = - 1 ⅔

Answer:

x ≈ 6.6 cm

Step-by-step explanation:

The Pythagorean theorem applies. The sum of the squares of the legs of this right triangle equals the square of the hypotenuse:

x^2 + 13.5^2 = (x+8.45)^2

x^2 +182.25 = x^2 +16.9x +71.4025

110.8475 = 16.9x . . . . . subtract x^2 +71.4025

6.559024 = x . . . . . . . .divide by 16.9

The value of x is about 6.6 cm.
