A. and ir ≠ 0 .............
Answer:
Rotation
Step-by-step explanation:
A transformation of a triangle can be either dilation or reflection or rotation or a translation.
Dilation happens when a symmetric figure is formed with scale factor other than 1. But here both triangles have same side length. Hence no dilation
Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on a line. Hence no reflection
Rotation is keeping the same shape but rotating through a certain angle. Here DEF is rotated without disturbing its shape or size through a certain angle. Hence rotation is right
Translation is not right because there is no vertical or horizontal shift to get new triangle.

Answer:
(x + 8) (x-8)
Step-by-step explanation:
x^2-64
Solve
a^2 - b^2 = (a+b) (a-b)
Where a = x , b = 8
(x + 8) (x-8)
Its 12, becuse if its a Circle then you can look at it the same way you look at a clock which has 12 numbers on it and 4 and 11 are directly across each other.
It would be 1,808.64 in2 because you find the area of the circle using a=πR²
