Answer:

Step-by-step explanation:

A polynomial is in its standard form when arranged in descending order based on the variable involved.

Looking at the provided polynomial

• s is presented in descending powers
• r is in ascending order

Thus, the first term of the polynomial should meet these criteria:

• Power of r is less than 2
• Power of s is greater than 4.

The following meets these requirements:

Answer:

Step-by-step explanation:

Denote the rectangular prism's volume as VR and the volume of the right triangular prism as VT. Given that the rectangular prism's volume exceeds that of the triangular prism by 32 cubic feet, we establish that VR = 32 + VT.

Calculating VR: VR = length * width * height = 6*x*3.

This simplifies to VR = 18x ft³.

For the triangular prism, VT can be calculated as Length * width * Height / 2, yielding VT = (7 * x * 4) / 2.

Thus, VT = 28x / 2, which simplifies to VT = 14x ft³.

Equating VR to 32 + VT allows the substitution: 18x = 32 + (14x).

Now, simplify the equation:

Combine like terms: 18x - 14x = 32.

This results in 4x = 32.

Dividing both sides by 4:

x = 8.

The volume for the rectangular prism comes to 18x, which equals 18*8.

The volume of the rectangular prism calculates to 144 ft³.

The volume for the right triangular prism calculates to 14x, which equals 14*8.

The volume of the right triangular prism calculates to 112 ft³.

Answer:

and expressed in interval notation.

Step-by-step explanation:

A compound inequality has been provided. Our task is to determine the solution for this inequality.

Initially, we will address each inequality independently, followed by merging the findings by combining the overlapping intervals.

By dividing with a negative number, it is necessary to reverse the inequality sign:

Again, dividing by a negative requires flipping the inequality sign:

In combining both intervals, we will arrive at:

Thus, the solution for the inequality provided is and in interval notation.

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.
