Answer:
Step-by-step explanation:
10x^2(3x^2 - 5x) Remove the brackets (Distributive Property)
10*3*x^2 * x^2 - 5x * 10x^2
30 x^(2 + 2) - 5*10x^(2+1)
30x^4 - 50x^3
N+(n+2)+(n+4)=165
add everything together to get
3n+6=165
Subtract 6 from each side
3n=159
divide by 3
n=53
the numbers are 53,55,57
<u>ANSWER:
</u>
The engine have 5.39 qt approximately.
<u>SOLUTION:
</u>
Given, a specific cars engine has a capacity of 5.1 L of oil.
We need to find how many quarts of oil does the engine have?
Number of quarts of oil is product of number of liters of oil and the number of quarts per liter.
We know that, one liter of liquid contains 1.056 quarts approximately.
Number of quarts of oil = number of liters of oil x number of quarts per liter.
Number of quarts of oil = 5.1 liters x 1.056 quarts.
Number of quarts of oil = 5.1 x 1.056
Number of quarts of oil = 5.389 qt.
Hence, the engine have 5.39 qt approximately
