Which property explains why these two expressions are equal?

Re-written, I believe the equation is:

(W+23)+5=W+(23+5)

With this, the parenthesis have nothing multiplying into it, so we can drop the parenthesis to get:

W+23+5=W+23+5
Which is the same thing.

So I'd assume it is the Associative property, because you are combining the like terms of 23 and 5.

Hope this helps!

Answer:

hii

Step-by-step explanation:

Answer:

  y = -x +3

  m = -1

  b = 3

Step-by-step explanation:

To solve the given equation for y, divide by the coefficient of y.

  (-3y)/(-3) = (3x -9)/(-3)

  y = -x +3

__

The slope is the x-coefficient, M = -1.

__

The y-intercept is the added constant, B = 3.

__

Both equations are graphed in the attachment. Texture has been added to the original so you can see the graphs are the same line.

<span>For this case, what you must do is find the area of the two rectangles shown in the figure.</span>

<span> We have then:</span>

<span> Rectangle 1:</span>

<span> A1 = (40) * (18)</span>

<span> A1 = 720</span>

<span> Rectangle 2:</span>

<span> A2 = (24-18) * (40-30)</span>

<span> A2 = (6) * (10)</span>

<span> A2 = 60</span>

<span> The area of the composite figure is:</span>

<span> A = A1 + A2</span>

<span> A = 720 + 60</span>

<span> A = 780 feet ^ 2</span>

<span> Answer:</span>

<span><span><span><span> the area of the figure is:</span></span></span></span>

<span><span><span> <span>C. 780 ft ^ 2</span></span>
