Question

Square A is a Dilation of Square B. What is thescale factor of the squares? (remember to donew/old)A.) 7B.) 4/5C.) 1/7D.) 5/4

Answer 1

Let x be the dilation factor, then we can write

`28x=35`

If we move 28 to the right hand side, we get

`\begin{gathered} x=(35)/(28)=(7\cdot5)/(7\cdot4) \\ \text{then} \\ x=(5)/(4) \end{gathered}`

therefore, the answer is option D
