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

Step-by-step explanation:

Step 1: Define

Point E (9,0)

Point F (0, -10)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(0-9)^2+(-10-0)^2}$
Subtract: $d = \sqrt{(-9)^2+(-10)^2}$
Exponents: $d = \sqrt{81+100}$
Add: $d = \sqrt{181}$
Evaluate: $d = 13.4536$
Round: $d \approx 13.5$

X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4

Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
