Well what you need to do is <span>find the perimeter of both rectangles.
Rectangle A: ((2x+8)*2)+((x-1)*2)
Rectangle B: ((3x + 5)*2)+((2x-2)*2)
That will be </span>(10x+6)-(6x+14)=4x-8
Your answer will be D.
Hope this is useful
Answer:
slope is 2/3
Step-by-step explanation:
from the point (0,0) you go up y by 2, and you go right by x by 3, y/x=2/3, to get to the next point of interception.
Answer:
Step-by-step explanation:
your answer is x>37
We know that the parabola opens downwards because it has a negative leading coefficient.
<h3>
</h3><h3>
Why the parabola opens downwards?</h3>
For any polynomial, the leading coefficient is the coefficient in the term where is the large exponent of the polynomial.
The sign of that coefficient will determine the end behavior of the graph of the polynomial.
For the case of the parabola, a positive leading coefficient means that the parabola opens upwards, while a negative leading coefficient will mean that the parabola opens downwards.
Now, if you look at our parabola:
g(x) = -(x + 1)^2 - 3
You can see that there is a negative sign, thus when we expand the parenthesis, we will end up with a negative leading coefficient:
g(x) = -x^2 - 2x + 1 - 3 = -x^2 -2x - 2
So we know that the parabola opens downwards.
