Answer and Explanation:
If the rectangle is dilated by a scale factor of 2, that means that all of its sides are doubled.
(a) Originally, AB = CD = 15
So, we just multiply 15 by 2: 15 * 2 = 30. Now, A'B' = C'D' = 30 cm
Originally, AC = BD = 8
We just multiply 8 by 2: 8 * 2 = 16. Now, A'C' = B'D' = 16 cm
(b) Basically, the drawing will be of a new rectangle with dimensions of 30 cm by 16 cm.

Answer:
x = -1
Step-by-step explanation:
2x + 3(2) = 4
2x + 6 = 4 Multiply 2 and 3 to get 6.
2x = -2 Subtract 6 from both sides to isolate 2x.
x = -1 Divide both sides by 2 to find x.
