A submarine is cruising 8 meters below the surface. The captain orders a dive of another 17 meters. What is the new cruising dep

swat32

Answer:

25 meters.

Step-by-step explanation:

Given in the question that,

Initial depth of the submarine = 8 meters

After the order of the captain, the submarine was made to dive another 17 meters.

So, the final cruising depth of the submarine can be calculated by adding the initial depth of the submarine and the depth further increased upon the order of the captain.

Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.

What is the quotient (125 – 8x3) ÷ (25 + 10x + 4x2)? –2x + 5 2x – 5 –2x – 5 2x + 5

Anit [1.1K]

For this case we have the following expression:

$\frac{125-8x^3}{25+10x+4x^2}$

Factoring the numerator we have:

$\frac{-(2x+5)(4x^2+10x+25)}{25+10x+4x^2}$

Rewriting the denominator we have:

$\frac{-(2x+5)(4x^2+10x+25)}{4x^2+10x+25}$

Canceling similar terms we have:

$-(2x+5)$

$-2x-5$

Answer:

The quotient of the division is given by:

$-2x-5$
