Can someone make the numbers 1 to 50 a perfect square?

Answers

I don't think you mean a "perfect" square. A perfect square is a whole number
that is the product of a smaller whole number multiplied by itself.
1, 4, 9, 16, 25, 36, and 49 are the perfect squares that are less than 50.

I think you mean a "magic" square ... one in which each row, each column,
and each diagonal, all add up to the same number. If that's what you mean,
then the answer to the question is "no". Magic squares are always square.
That is they always have the same number of rows and columns. So the
number of 'cells' in a 'magic' square is always a 'perfect' square.

50 isn't a perfect square, so you can't make a magic square with it.

Find last year's salary if, after a
5 % pay raise, this year's salary is
$34,125.

Answers

Let last year's salary be y;
As a percentage, last year's salary was 100%
After a 5 percent raise, the new salary is 105%;
The 105% is equivalent to 34,125;
The older salary was;
= $(34125*100)/(105)$
= 32,500 dollars

Multiply: (4x – 7)(2x – 9)

Answers

Hello there!

Let's use foil.

First: 4x * 2x = 8x^2

Outside: 4x * -9 = -36x

Inside: -7 * 2x = -14x

Last: -7 * -9 = 63

Now, let's combine these.

8x^2 - 36x - 14x + 63

Finally, we can simplify this

8x - 50x + 63

I hope I helped!

Let me know if you need anything else!
