Lines of longitude
The prime meridian passes through Greenwich in London UK.
AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1
Answer: Rigid just means that the whole shape goes through the same transformation, so with rotations, reflections, and translations, the shape should not change at all, just in a different place or orientation.
In a translation, ALL of the points move the same distance in the same direction. A translation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image. ... In addition, the corresponding segment sides of the pre-image and image are parallel.
A rigid transformation preserves both the side lengths and the angle measures of a polygon. Step-by-step explanation: Rigid transformations are the transformations which does not affect the size and the shape of figure . The figure doesn't shrink or get enlarger.
There are three different types of transformations: translation, reflection, and rotation.
The distance from each point in the figure to the center of rotation is preserved. A rigid transformation is a transformation that preserves congruence.

Answer:
b = 1/2
Step-by-step explanation:
6x + 2 = 5
6x = 3
x = 1/2
1) Y=x-3, if the output value is “5”, then we can rewrite it as 5=x-3. Then add 3 to both sides, so x=8.
2). If the function says to add 6 to the input, and the output is 6, then the input must be 0.
Or put another way, 6=x+6, x can only be 0.
