Answer:

Step-by-step explanation:

2(6x² - 3) = 11x² - x

2*6x² - 2*3 = 11x² - x

12x² - 6 = 11x² -x

Subtract 11x² from both sides

12x² - 11x² - 6 = -x

x² - 6 = -x

x² + x - 6= 0

Sum =1

Product = -6

Factors =  3 , (-2)              { 3*(-2)  = -6   & 3 +(-2) = 1}

x² + 3x - 2x - 6 = 0

x(x + 3) - 2(x + 3)= 0

(x +3)(x - 2) = 0

Tony's dorm is 7.5 miles far from the library.

Step-by-step explanation:

Given points are;

(4,0) and (12,6)

x_1=4,\ \ \ \ \ \ \ y_1=0\\x_2=12,\ \ \ \ \ \ y_2=6

Using point distance formula;

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance=\sqrt{(12-4)^2+(6-0)^2} \\Distance=\sqrt{(8)^2+(6)^2}\\Distance=\sqrt{64+36}\\Distance=\sqrt{100}\\Distance=10\ units

One unit represents 0.75 miles, therefore,

10 units = 0.75*10 = 7.5 miles

Tony's dorm is 7.5 miles far from the library.
