Answer:
The height on the plans is 6.5 inches
Step-by-step explanation:
1 inch of plan = 5 inch of dollhouse
we know the dollhouse is 32.5 inches, so we need to determine the unknown
x inch of plan = 32.5 inch of dollhouse
x = 32.5/5 = 6.5 inches
The given identity tells you ...
.. (sum of numbers) * (sum of squares - product) = (sum of cubes)
Substituting the given information, you have
.. (sum of numbers) * (29 -10) = 133
Then you can divide by (29 -10) to get
.. sum of numbers = 133/19 = 7
The sum of the two numbers is 7.
