The answer is 4.

The formula for the area of a rectangle is A = lw. Substitute, so then it's 28 = (3x-5) * x, and you evaluate.

Hope this helps you! And rate so I can see if I did well!

Parallelogram ABCD has vertex coordinates A(0, 1), B(1, 3), C(4, 3), and D(3, 1). It is translated 2 units to the right and 3 un
Ivenika [448]

Answer:  The correct option is (C). (-2, 2).

Step-by-step explanation:  Given that the co-ordinates of the vertices of parallelogram ABCD are A(0, 1), B(1, 3), C(4, 3), and D(3, 1). The parallelogram ABCD is translated 2 units to the right and 3 units down and then rotated 180 clockwise around the origin.

We are to find the co-ordinates of the vertex A after the transformation.

We know that if the point (x, y) is translated a units right and b units down, then its new co-ordinates will be (x + a, y - b).

So, the co-ordinates of point A after translation of 2 units to the right and 3 units down are

(0 + 2,  1 - 3) = (2, -2).

Now, a rotation of 180° clockwise will change the co-ordinates (x, y) to (-x, -y).

Therefore, the final co-ordinates of point A are

(2, -2)  ⇒ (-2, 2).

Thus, the new co-ordinates of A are (-2, 2).

Option (C) is CORRECT.

Diego plans to build an extension to his rectangular model bridge. Let x represent the increase, in centimeters, of the model's
marishachu [46]

Answer:

(21x+168)cm²

Step-by-step explanation:

If the expression 2 1 (x + 8) represents the area of the model bridge, where 2 1 is the width, in centimeters, and (x + 8) represents the extended length, the expression that is equivalent to 21(x+8) can be gotten by expanding the function. The expansion of the function will give the area of the rectangular model bridge as shown;

21(x+8) = 21x+ 168

The expression equivalent to 21(x+8) is therefore (21x+68)cm²

Note that the the unit of the value and function given is in cm therefore the unit of their equivalent expression will be in cm²
