209÷2=104.5
104.5 is the number between the two consecutive integers, therefore the first number would be 104 and the other would be 105
104+105=209
Im assuming there is exponents so if im assuming correctly, then the answer would be 6x^4 - x^3 - 5x^2 + 10x + 5 because you would combine like terms.
Answer:

Step-by-step explanation:
<u>Find the volume of separate cuboids</u> :
<u>Volume (top cuboid)</u> :
⇒ V = 2 x 6 x (10 - 2)
⇒ V = 12 x 8
⇒ V = 96 cm²
<u>Volume (lower cuboid)</u> :
⇒ V = 8 x 6 x 2
⇒ V = 48 x 2
⇒ V = 96 cm²
<u>Volume (prism)</u> :
⇒ 96 + 96
⇒ 192 cm²
The 1.8 s is the time for the signal to reach the ocean floor and return to the ship so the time to reach ocean floor = 1.8 / 2 = 0.90 seconds.
depth of ocean = speed * time
= 1498 * 0.90 = 1348.2 m Answer
