21x³ - 18x²y + 24xy²
Simplify!
7x³ - 6x²y + 8xy²
This is simply a question about ratios. This ratio means that for every 1 cm on the map, there are 12 km in actuality. You can set this problem up in fractions:
1 cm 12 cm
-------- = ----------
12 km x
To solve for x, we cross-multiply, for the moment ignoring units. Remember, your answer will be in km.
1*x=12*12
x=144
If x=144, then for 12 cm, there are 144 km.
Is about the same as the posting you had before.
bear in mind that in an exponential equation the initial amount is usually the one outside the parentheses, the one that doesn't have an exponent
128(0.50)ˣ, that'd be 128.
