What do u need for this explain and and will help?
Answer:
m = -3
Step-by-step explanation:
<span>Let y= original side
So
A = LW
60 = (y+15)(y-13)
(y+15)(y-13) = 60
y^2 + 2y - 195 = 60
y^2 + 2y- 195 - 60 = 0
y = -17 or y= 15
Toss out the negative solution to get y= 15 as the only solution.
So the square has a side length of 15 meters.
The area of this square is 15^2 = 15*15 = 225 square meters.</span>

Answer:
(d) No, the figures are different sizes
Step-by-step explanation:
Congruent figures have corresponding sides the same length. A'''B''' is not the same length as AB, so the figures cannot be congruent.
__
Congruence is sometimes shown by identifying rigid transformations that map one figure onto another. Rigid transformations preserve size. The sizes these figures are different, so rigid transformations cannot be used to map one figure to the other. The appropriate statement of this is choice D.
C is the answer 10 because 10 is the answer 10 is the number that was repeated the most so its the mode
