Answer:x=11
Step-by-step explanation:
the answers are a and b and c
The correct answer is: 17280 <span>
cubic inches</span>
Explanation:As we are going to convert bigger unit (feet) into small unit (inches), we will need to multiple 10 with

as there are 12 inches in 1 foot and the unit is in cubic form, therefore, we would need to take the cube of 12. Mathematically we can write it as:

<span>cubic inches
Hence the correct answer is </span>17280 cubic inches.
To solve this, set up a function where w is the number of weeks and h(w) is the number of houses made per week. As you produce 3 houses a week, your function would be h(w)=3w. Now, as you want to produce 54 houses, set your h(w) equal to 54, making your function 54=3w. Now, solve for w, divide both sides by 3, w=54/3=18. This means your answer is 18 weeks.
