Answer:
B
Step-by-step explanation:
Consider all options:
A. Transformation with the rule
is a reflection across the x-axis.
Reflection across the x-axis preserves the congruence.
B. Transformation with the rule
is a dilation with a scale factor of over the origin.
Dilation does not preserve the congruence as you get smaller figure.
C. Transformation with the rule
is a translation 6 units to the right and 4 units down.
Translation 6 units to the right and 4 units down preserves the congruence.
D. Transformation with the rule
is a clockwise rotation by angle over the origin.
Clockwise rotation by angle over the origin preserves the congruence.
A = length x width
15,000 = (w + 30) x w
15,000 =
+ 30w
0 = + 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5
. Because distance cannot be negative, the width is -15 + 5meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
15,000 = (w + 30) x w
15,000 =
