Answer:

8x = 56

Step-by-step explanation:

Solve for x by isolating it.

<em>Divide both sides by </em><em>4</em>

(x-3) = 4

<em>Add </em><em>3</em><em> to both sides</em>

x = 7

<em>Now plug </em><em>7</em><em> in for </em><em>x</em>

8(7) = 56

ABDE is a rectangle on coordinate axes, the sides of the rectangle are parallel to the axes,
Hitman42 [59]

The coordinates of B and D are the location of the vertices B and D in the rectangle

The coordinates of B and D are (55, 30) and (55, 14)

<h3>How to determine the coordinates of B and D?</h3>

From the figure of the rectangle, we have:

A = (25,30)

C = (40, 22)

Point B has the same y-coordinate as point A

So, we have:

B = (x, 30)

The x-coordinate is then calculated as:

Bx = 2Cx - Ax

This gives

Bx = 2*40 - 25

Bx = 55

So, the coordinates of B are:

B = (55, 30)

Point D has the same x-coordinate as point B

So, we have:

D = (55, y)

The y-coordinate is then calculated as:

Dy = Cy - (By - Cy)

This gives

Dy = 22 - (30 - 22)

Dy = 14

So, the coordinates of B are:

D = (55, 14)

Hence, the coordinates of B and D are (55, 30) and (55, 14)
