I think what you're looking for is the 3 x 3 "magic square".
It looks like this:
[ 8 ] [ 1 ] [ 6 ]
[ 3 ] [ 5 ] [ 7 ]
[ 4 ] [ 9 ] [ 2 ]
Every row, column, and diagonal adds up to 15.
To solve a 3x3 magic square with decimals, you need to ensure that the sum of numbers in each row, column, and diagonal is equal. Start by placing the decimal numbers in a way that each row, column, and diagonal sums up to the same value. Adjust the numbers carefully to achieve a valid solution.
Factor it! Set each equal to zero! Solve
15 and 15
You set the two equations equal to each other and then solve for the variable.
Yes, and even more than that: equal numbers of each kindof atoms.
The two numbers that times eachother to equal to 63 are 9 and 7........... (9x7=63)
The numbers are: 30 and 5
56
Compare numbers.
I believe it would be both numbers or none at all.
Set each factor, in turn, equal to zero and solve for x.
No - the two numbers are equal to each other.
