tina solved a quadratic equation and found the solution to be -3/2 and 6 which of the following is equivalent to the quadratic e
Bond [772]

Answer:

x^2-\dfrac{9}{2}x-9=0

Step-by-step explanation:

The solutions of a quadratic equation are :

x = -3/2 and x = 6

or we can write it as :

x+\dfrac{3}{2}=0\ and\ x-6=0\\\\(x+\dfrac{3}{2})(x-6)=0

Multiplying both values,

(x+\dfrac{3}{2})(x-6)=0\\\\x^2-6x+\dfrac{3}{2}x-9=0\\\\x^2-\dfrac{9}{2}x-9=0

Hence, the required quadratic equation is x^2-\dfrac{9}{2}x-9=0.

A car can go 35 1/2 miles in 1 1/2 miles gallons. How many gallons does a car need to go 639 miles?
Mnenie [13.5K]

Answer: 27 gallons

Step-by-step explanation:

Since the car can go 35½ miles in 1½ miles gallons, we need to first calculate the number of miles that the car can go in 1 gallon. This will be:

= 35½ / 1½

= 71/2 / 3/2

= 71/2 × 2/3

= 23⅔ miles per gallon.

Therefore, the amount of gallons that the car need to go 639 miles will be:

= 639 / 23⅔

= 639 ÷ 71/3

= 639 × 3/71

= 27

The car will need 27 gallons.
