question 13
this scale drawing shows an enlargement in a figure.
what is the value of x?

Explanation:

Step1: Set up proportion

Since the figures are similar, the ratios of corresponding sides are equal. We have the proportion $\frac{10}{14}=\frac{4}{x}$.

Step2: Cross - multiply

Cross - multiplying gives us $10x = 4\times14$.

Step3: Simplify right - hand side

$4\times14 = 56$, so $10x=56$.

Step4: Solve for x

Dividing both sides by 10, we get $x=\frac{56}{10}=5.6$.

Answer:

$5.6$
