### Mathematics the sum of two numbers is 20 if the product is 51, calculate the value of the Two numbers

Let's take it one step at a time.
First part of the sentence uses the word sum. Sum = Addition
Later, the word product. Product = Multiplicaton
Rephrasing, we want two number that add to 20 and multiply to 51.

Let a be the first number.

Let b be the second number.

a + b = 20
a x b = 51

You either solve this in your head, by trial and error. The next step I take is to factor the a x b or 51. The factors are 1, 3, 17, and 51.

Which of these numbers add to 20? 17 and 3.

Good luck,

Paul

### -54k^2+3k

-54k^2+3k I assume that you want to factor this completely.
I do it one component at a time.
What is the biggest common factor of -54 and 3. I use a trick of adding the digits of the number. If 3 and/or 9 go into that number evenly, than 3 and/or 9, respectively go into the original number. In this case, 5+4 = 9 and since 3 goes into 9 evenly, 3 goes into 54 evenly. Since the factors of 3 are 3 and 1, this must be the greatest common factor of this component.
Onto the next component, what is the greatest common factor of k^2 and k. The answer is k, because k^2 doesn't go evenly into k.
Combining the two, the greatest common factor is 3k.

Next we have to divide 3k into each term.
3k(-18k+1) or -3k(18k-1)

Good luck,

Paul

### I'm trying to figure out a 3x3 magic square where the rows equal 21 18 10 and the columns equal 15 24 13 using the numbers 1-9

I don't think you can do it! Could you check your numbers.

If we are using the numbers 1-9 once and only once in a 3x3 magic square, the sum of the rows + the sum of the columns should be 90, since 1+2+3+4+5+6+7+8+9 in the rows adds up to 45 and 1+2+3+4+5+6+7+8+9 in the columns adds up to 45.

When trying to solve, the magic number seem to be the sums 24 and 10. To get 24, the only three numbers that add to 24 are 7 + 8 +9. Similarly to get 10, the lowest numbers re 1 and 2 and the smallest big number to use is 7. I then ran out of number trying to get 21, 13 and 15 sums.

Good luck,

Paul

### Is 450 divisible by 3 in fractions

450=9*5*10=9*50
9*50/3=3*50=150
To verify if a number is divisible by 3, add the digits in the number. If the sum of digits is divisible by 3, then thumber is also divisible by 3.
Sum of digits in 450 =4+5+0 =9, divisible by 3, so 450 is also divisible by 3.

### What are the factors of 72

hello. now you are making me think about something that i have not thought about in many years.

72 is a composite number because it has factors other than 1 and itself., It is not a prime number.

The 12 factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
The factor pairs of 72 are 1 x 72, 2 x 36, 3 x 24, 4 x 18, 6 x 12, and 8 x 9.

The proper factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36 or,
if the definition you are using excludes 1, they are 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36. The prime factors of 72 are 2, 2, 2, 3, and 3.
