Hi,
Let's solve the equation step-by-step.
x2+10x−2=0
Step 1: Use quadratic formula with a=1, b=10, c=-2.
x=
−b±√b2−4ac / 2a
x= −(10)±√(10)2−4(1)(−2) / 2(1)
x= −10±√108 / 2
x=−5+3√3 or x=−5−3√3
Answer:
x=−5+3√3 or x=−5−3√3
Have a great day!

Infinite Solutions
Step-by-step explanation:
x + y = 4
y = -x + 4
x + y = 4
x - x + 4 = 4
0 = 0
Answer:
I'm gonna use the distance formula:
Distance = sqrt((x2-x1)^2 + (y2-y1)^2)
Distance = sqrt((6-3)^2 + (13-9)^2)
Distance = sqrt(3^2 + 4^2)
Distance = sqrt(9 + 16)
Distance = sqrt(25)
Distance = 5
The problem says every unit = 1 mile so 5 units = 5 miles.
