Answer:

67.5

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the enlargement or reduction of an object by a factor.

The area of ABCD = AB * BC = 30

As a result of the dilation to form A'B'C'D', A'B' = 3/2 * AB, B'C' = 3/2 * BC, C'D' = 3/2 * CD and A'D' = 3/2 * AD. Hence:

Area of A'B'C'D' = A'B' * B'C' =  3/2 * AB * 3/2 * BC = 9/4 * (AB * BC) = 9/4 * 30 = 67.5

Evaluate c/2 - 3 + 6/d when c=14 and d=13???
Kazeer [188]

c/2-3+6/d

substitute c=14 and d=13:

14/2-3+6/13

simplify:

7-3+6/13

4+6/13

multiply 4 by 13/13 to group like terms (for a fraction):

52/13+6/13

combine:

58/13

Therefore, the answer is 58/13 or around 4.462
