Which of these properties of a rigid transformation is exclusive to translations?
A. The measures of the angles and sides in the preimage are preserved.
B. The points in the preimage lie in the same plane as the points in the image.
C. All the points in the preimage are shifted the same distance.
D. The orientation of sequences of points in the preimage are always preserved.

C. All the point in the pre-image are shifted the same distance.

Step-by-step explanation:

It's not A because for example, a rotation also preserves the angles and sides.

It's not B because the points stay in the same plane for all transformations.

It.s not D -  the orientation is the same in a rotation.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
