Answer:
x = 7
Step-by-step explanation:
Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':
Cross-multiply: 3(x + 1) = 6(x - 3)
Distribute: 3x + 3 = 6x - 18
Combine like terms: 21 = 3x
Solve for 'x': x = 7
<h3>Answer: a = -3 and b = 5</h3>
=================================================
Work Shown:
Multiply top and bottom by to rationalize the denominator
We end up with something in the form where a = -3 and b = 5
