Answer:
(4k^2+7)(7k+6)
Step-by-step explanation:
1. group the first two terms (28k^3-24k^2). The greatest common factor is 4k^2. If you factor that out you get 4k^2(7k-6)
2.When you group the last two terms (49k-42). you can factor out a 7.
7(7k-6).
3. There is a (7k-6) in both sections so you can combine all the terms.
4k^2(7k-6) 7(7k-6) becomes (4k^2)(7k-6)

Answer:
<em>Reflecting over the x-axis and then reflecting over the line y = x. </em>
Step-by-step explanation:
<em>A rotation 90° counterclockwise will map every point (x, y) to (-y, x).</em>
<em></em>
<em>Since the x- and y-coordinates are switched, this is not a reflection across the x-axis followed by a reflection across the y-axis.</em>
<em></em>
<em>Since the y-coordinate is negated and the x- and y-coordinates are switched, this is not a translation.</em>
<em></em>
<em>Reflecting across the x-axis will negate the y-coordinate, giving us (x, -y). Following this with a reflection across y=x will switch the coordinates giving us (-y, x). This is the correct transformation.</em>
