Well I am so sry what is ur question lilololilokok
For
ax+by=c
the slope is -a/b
the slope of paralell lines are the same
fidn slope
5x+3y=15
-a/b=-5/3
paralell as same slope
answer is A
We want to make x^2-3x into a perfect square trinomial. An example of such a trinomial is x^2 + 6x + 9, which is equivalent to the square of (x+3).
From x^2-3x we see that the coefficient of x is -3. Divide this coefficient, -3, by 2, obtaining -3/2. Now square this result: square -3/2. Result: 9/4.
Adding 9/4 to x^2-3x makes x^2-3x into a perfect square trinomial.
If the area of the entire thing is 21.66 square inches, you can do the area of the entire thing-the area of the rectangle. This is, 21.66-4.6*3.8. 21.66-17.48, which =4.18.
