Answer:

5x-1.

Step-by-step explanation:

We have been the formula for the volume of a rectangular prism as: V = 5x^3+29x^2+34x-8 and the lengths are (x+2) and (x+4).

Since we know that volume of a rectangular prism is length times width times height, so to find the our missing length we will divide volume of rectangular prism by the given side length.

\text{Missing side}=\frac{5x^3+29x^2+34x-8}{(x+2)(x+4)}

\text{Missing side}=\frac{5x^3+29x^2+34x-8}{x^2+6x+8}

\text{Missing side}=\frac{(5x-1)(x^2+6x+8)}{x^2+6x+8}

\text{Missing side}=(5x-1)

Therefore, missing length of the rectangular prism is 5x-1.

Answer:

2) distance = 4 km

Displacement = 4 km east

3) distance = 35 km

Displacement = 5 km north

Step-by-step explanation:

2. He runs for 3 km in the east direction and then stops.. He now runs another 1 km in the same direction then stops.. Thus,

Total distance covered = 3 + 1 = 4 km

Total displacement is how far he is from his starting point = 3 + 1 = 4 km east

3) Runs 20km north and then runs 15 km back from starting point.

Thus;

Total distance covered = 20 + 15 = 35 km

Total displacement is distance from starting point = 20 - 15 = 5 km north

Subtracted because an opposite direction was taken after the 20km back to her starting point.
