This is telling you to find out the dimensions of her house.
I suggest using mathpapa for each equation. It will show you how to solve it and then the answer.
So for the top dimensions, put the following into mathpapa: (2x-10)+(x-2)+(.5x-4)+(x-2)
Answer:
2x > 10+4
x > 14/2
x > 7
Step-by-step explanation:
18/6
18= the number of trucks
6= the number of hours
18/6= 3 trucks per hour
