Answer:
b. 0.86, 0.87
Step-by-step explanation:
a. Refer to the attached solution for part a
The formula representing this scenario is 
The answer to this formula is 
Initially, you need to formulate the equation.

Next, simplify the expressions.

Afterwards, subtract 5.7 from both sides.

Lastly, divide both sides by 5

Answer:
Step-by-step explanation:
For resolution, the Euclidean division is necessary:
- The polynomial is expressed as 16-2x³-6x²+x+9=-2x³-6x²+x+9
- We will divide this by: 4+3x-2=3x+2 and analyze the remainder
A visual representation of the process is provided
- The remainder is 47/9, hence the value to subtract is 47/9
The dimensions of the book cover are 28.3 centimeters in length and 21 centimeters in width. Calculate the range of values for both the actual length and width of the book cover. Minimum length = (28.3 - 0.05) cm and maximum length = (28.3 + 0.05) cm, thus 28.25 cm ≤ length < 28.35 cm.
