What value of w makes this multiplication sentence true? 28 · (824 + 514) = 28 · 824 + 28 · w

vivado [14]

Answer:

514

Step-by-step explanation:

First, we need to find the value of the non-variable side.

824+514 =1,338.

1,338 multiplied by 28 is 37,464.

So now we have : 37, 464 = 28* 824 + 28* w

28* 824 is 23,072.

And then we have, 23,072 * 28w.

Subtract 37,464 by 23,072on both sides, which is equal to 14,392 = 28w

Finally, divide 14,392 by 28 on both sides to get 514 = w

Therefore, w is 514.

Good luck mate, hope this helps.

Quadrilateral ABCD has vertices A(-2,4), B(-3.-3), C(-5,-2), D(-5,2). Which of the following are the coordinates of A’ after a d

<h2>Answer:</h2>

$\boxed{A'(-5,10)}$

<h2>Step-by-step explanation:</h2>

Dilation is when you stretch something by the same amount in two perpendicular directions. In other words, dilation changes size, not overall shape. Dilation factors greater than one makes the shape greater while dilation factors less than one makes the shape smaller. The scale factor in this problem is:

$2\frac{1}{2}$

Which is a mixed fraction. This can be transformed into an improper fraction as follows:

$2\frac{1}{2}=2+\frac{1}{2}=\frac{4+1}{2}=\frac{5}{2}$

So the scale factor is $\frac{5}{2}$ . Since the center of dilation is the origin, we just need to multiply each vertex of the quadrilateral by the scale factor. Thus, for A we have:
