Answer:
Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
In this item, we are already given that the length of the rectangular book can be represented by the variable x. In this way, the width, which was described to be the difference of the length and 3 inches, can be expressed as x - 3.
The area of the triangle is rectangle is calculated by multiplying the length, x, and the width, which was derived to be x - 3.
Area = Length x width
Area = (x)( x - 3)
Putting in the value of the area, we have the final answer as,
x(x - 3) = 63.8 in²
Hence, the final answer is the first answer.

Step-by-step explanation:
Answer:
2 tons of dirt per hour
Step-by-step explanation:
helpful to know: 1/6 hours = 10 minutes
you can create a proportion to find unit rate by using (tons of dirt ÷ time)
we'll use 'd' to represent amount of dirt and use minutes
1/3÷10 = d/60
1/3÷10 = 1/3 × 1/10 = 1/30
we now have:
1/30 = d/60
we can cross-multiply to get:
30d = 60
d = 2
The difference between these two numbers is the digit '2' is being moved one decimal point to the left.
If this pattern continues, the next terms in the pattern would be: 0.2, 2, 20
