I think x = 4, but im not 100% sure so im sorry if it is wrong
30 of the divisors are multiples of 3
The factors of 2160 are 1, 2160, 2, 1080, 3, 720, 4, 540, 5, 432, 6, 360, 8, 270, 9, 240, 10, 216, 12, 180, 15, 154, 16, 135, 18, 120, 20, 108, 24, 90, 27, 80, 30, 72, 36, 60, 40, 54, 45, 48
These are all divisors of 2160 but only 30 are multiples of 3.
The ones that are NOT are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80
You can also do this using prime factors 2x2x2x2x3x3x3x5 = 2160 but it is harder to explain.
<span>The correct
answer is 3.24 grams per cubic centimetre. As a matter of fact, the
lunar soil’s mean density may range from 2.90 to 3.24 g cm-3 which highly
depends on the type of ingredients present in its resource materials.</span>
Answer:
The equation is adjusted by dividing the tax amount by the percent to find the original cost. Dividing by the percent is the inverse operation of multiplying by percent.
If this question is from edge 2021 it's 100% right.
To show: (x+y)² − (x −y)² = 4xy
Using difference of square identity:
Taking left side
hence proved
