54^2=54x54
=(50+4)(50+4)
=50^2 + 2x50x4 + 4^2
=2500 + 400 + 16

Answer:
10400km
Step-by-step explanation:
We know that the scale on a map is 1cm for every 400km. So to find the actual distance for 26cm on the map, we take 26 multiplied by 400km. This gives 10400km.
The first way:
1. Reflect the figure I across the x-axis.
2. Translate the figure I and its reflection and rotate them 90 degrees.
The second way:
1. Reflect the figure I across the x-axis.
2. Rotate 90 degrees counterclockwise.
3. Rotate it across the y-axis.
Points that lie on the same line are called collinear points
Collinear points are points that lie along a straight line or along the same line.
The next step she should take is to use her ruler to join the given point to the point where the arcs intersect.
<h3>Steps in constructing perpendicular lines</h3>
- Place your compass on the given point
- Draw an arc across the line on each side of the given point. Do not adjust the compass width when drawing the second arc
- From each arc on the line, draw another arc on the opposite side of the line from the given point. The two new arcs will intersect.
- Use your ruler to join the given point to the point where the arcs intersect.
- Use your compass and ruler to draw a perpendicular line from each given point to the line segment
From this, we can deduce that her next step is to use her ruler to join the given point to the point where the arcs intersect
Thus, the next step she should take is to use her ruler to join the given point to the point where the arcs intersect.
