What are the solutions of the equation (x - 6) (x - 8) =8

enot [183]

Answer:

x=4 x=10

Step-by-step explanation:

(x - 6) (x - 8) =8

We need to multiply out the left side

x^2 -8x -6x+48 = 8

x^2 -14x +48 = 8

Subtract 8 from each side

x^2 -14x +48-8 = 8-8

x^2 -14x+40 =0

We need to factor the left side. What two numbers multiply to give 40 and add to give -14

-4*-10 = 40

-4+-10 = -14

(x-4) (x-10) =0

Using the zero product property

x-4=0 x-10 =0

x=4 x=10

Two cars leave a town at the same time heading in opposite directions. One car is traveling 12 mph faster than the other. After

Katena32 [7]

<span>Find the speed of each car.
Let a be the first car
Let b be the second car
=> a = x miles per hour
=> b = x + 12 miles per hour
=> 2 (x+ x + 12) = 232 miles per hour
=> 2x + 12 = 232
=> 2x + 12 = 116
=> 2x = 116 - 12
=> 2x / 2 = 104 / 2
=> x = 52 (speed of Car A)
=> 52 + 12 = 64 miles per hour (speed of Car B)</span>
