Answer:
x= -6 twice
Step-by-step explanation:
x^2-3x-10/x^2+12x+36
By using undefined fraction we only take the denominator and equate it to 0
x^2+12x+36=0
x^2+6x+6x+36=0
(x^2+6x)+(6x+36)=0
x(x+6)+6(x+6)=0
(x+6)(x+6)=0
x+6=0 or x+6=0
x= -6 or x= -6
therefore x= -6 twice
Using the Pythagorean theorem:
15^2 = 12^2 + X^2
225 = 144 + x^2
X^2 = 225 - 144
x^2 = 81
x = √81
x = 9
The distance is 9 feet.
The answer is A.
