Answer:
AB=6 Units
Step-by-step explanation:
Given the following lengths of rectangle ABCD and its dilation A'B'C'D' respectively
- A'B' = 15 Units
- B'C' = 9.5 Units
- BC = 3.8 units
We are to determine the length of AB. To do this, we first determine the dilation factor.

Therefore:

Answer:
15
Step-by-step explanation:
Radius times 2 is the diameter!
Answer:
9x² + 12
Step-by-step explanation:
Area = Length × Width
Area = 3 × (3x² + 4)
Area = 9x² + 12
Answer:
56
Step-by-step explanation:
We just plugin -3 for all the x values. We get: 5(-3)^2+-3(-3)+2.
(-3)^2=9, -3(-3)= 9 because it is the same as (-3)^2.
We get 5(9)+9+2=>45+11=>56=>D.
