So amount minused=hours driven times gallons per mile=h times 2 or 2h
so we minus 2h
18-2h is the expression
(2n+4)x(4n+7)
= 8n^2+14x+16n+28
=8n^2+30n+28
that's it :) !!
You take away the 4 from the 8 which is equal to 4 then you have to barrow from the 2 to make the 4 to 14 and when you wait you are basically right your calculation is right
Answer:
He is 27 years old.
Step-by-step explanation:
27 is a multiple of 9 (9 x 3)
28 comes after, and is a multiple of 4 (4 x 7)
Hope this answer helps you!! :)
If x to the 12th power is divided by x to the 9th power:
Since they share same bases, and are being divided, it would be the same as x^{12 - 9), or x^{3}
Now, simply find the cube root of 125, which is 5.
Therefore, the number (x) must be equal to 5.
