Answer:
7-x
Step-by-step explanation:
49 - x^2 is a perfect square so
it factors to :(7+x)(7-x)
since there is a negative in 49 - x^2, it would make sense that the answer would be a negative to get that negative answer in the first place (negative times a positive equals a negative)
Forgive me for my lame explanation :')

➷ To find the mean you add together the values and divide by how many values there are:
150 + 100 + 120 + 200 + 180 + 300 + 250 = 1300
1300/7 = 185.714285
Median:
Order the values and find the middle one:
100, 120, 150, 180, 200, 250, 300
As you can see, it is 180
➶ Hope This Helps You!

Answer:
Correct option is C
Step-by-step explanation:
we have to tell that in which type of transformation angle are preserved.
Rotation:
This transformation turns a figure about a fixed point and the fixed point is known as the centre of rotation. The figures which goes through rotation has same angle as that of original figure.
i.e Rotation transformation preserves angle.
Reflections:
This transformation flip a shape over a line.
Angles also preserve in this type of transformation.
Translations:
This transformation involves sliding a shape. The figure only translate right left i.e shape or angle preserve i.e not changed.
Hence, the angles are preserve in in all three type of transformations that are rotation, reflection and transformation.
∴ Correct option is C
