It would be 1284 divided by 9 and then u round it which is 1284 / 9 =142.666 which can be rounded up to 140 or 143
Answer:
The scale factor, or linear scale factor, is the ratio of two corresponding side lengths of similar figures.

Answer:
y =
OR y = 
Step-by-step explanation:
Our quadratic equation is: (5y + 6)² = 24.
The first step is to square root both sides:
5y + 6 = ±√24 = ±2√6
Now subtract 6 from both sides:
5y = ±2√6 - 6
Finally divide by 5 from both sides:
y =
OR y = 
And, those are the solutions to the equation.
