The temperature at 5 am was -3 degrees
12-15=-3
90 volume because 3 multiples by 30 = 90
Solution
The dimension of the rectangular floor is 18ft long and 12 ft wide
Using the conversion table
It is given that 1yd =3 ft
This shows that
12 feet will be equivalent to

Also 18ft will be equialent to

Therefore the new dimension is 6 yard by 4 yard
The area will be

Therefore the required area is
The distance is 3, because 7 - 4 = 3.
Sum means to Add.
So the sum of d and 9 would be d + 9
