Answer:

97.8 liters

Step-by-step explanation:

We use proportions:

If 7.4 liters are needed for 100 km, then we can write the rate:

7.4 L / 100 km which should equal the rate for the x number of liters needed for a 1322 km trip:

7.4 L / 100 km = x / 1322 km

solving for "x" by multiplying both sides by 1322:

x = 97.828 liters

which we may be able to round to 97.8 liters

How do I get the answer for this quadratic equation in simplest form?

konstantin123 [22]

Answer:

x = 7 ± $\sqrt{15}$

Step-by-step explanation:

Given

4(x - 7)² - 48 = 12 ( add 48 to both sides )

4(x - 7)² = 60 ( divide both sides by 4 )

(x - 7)² = 15 ( take the square root of both sides )

x - 7 = ± $\sqrt{15}$ ( add 7 to both sides )

x = 7 ± $\sqrt{15}$
