Answer:
standard form
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
To solve this problem, start by identifying Rapunzel’s current hair length.
This is:
20, 193 centimeters.
Next, find her initial hair length.
This is:
19 centimeters
To solve for the length that her hair has grown, you must subtract the initial length (the smallest value) from the current length (the largest value).
This results in:
20,193 - 19
Subtract to find your final answer.
This leaves you with:
20,174 centimeters.
So, Rapunzel’s hair has grown 20,174 cm in the past 10 years.
I hope this helps! :)
