System of equations
2x + 3y = 79
x + y = 28
So what do you want to know about it? We need more info on this.
The range of the data is C. 160 because the biggest number, 280, subtracted by the smallest number, 120, is equal to 160.
The difference between 342 and 324 is different because the digits 2 and 4 are flipped.
342 and 324 are alike because they have the same amount of digits. hope that helped.
To create a perfect square trinomial, halve the x coefficient, square it, and then add that value.
In the case of x² + 6x, we would have 6 to get 3, then square 3 to get 9.
We would add 9 to make a perfect square trinomial.
<u>
</u><u>Why this works</u>
A perfect square trinomial is designed to factor to some value (x+n)².
When you FOIL this you get x² + 2nx + n².
As you can see, if you wanted to find the value of that n², you could take that x coefficient 2n, halve it to get n, and then square it to get n²!
