For this case we have:

By definition, the distributive property states that:

(a + b) (c + d) = ac + ad + bc + bd

In addition, we know that: ax * bx = (ab) x ^ 2, that is, the exponents are added together.

If we have:(4y - 3)\ and\ (2y ^ 2 + 3y - 5), your product is given by:

(4y - 3) (2y ^ 2 + 3y - 5) = (4 * 2) y^{1 + 2} + (4 * 3) y^{1 + 1} - (4 * 5) y^{1 +0} - (3 * 2) y ^ {0 + 2} - (3 * 3) y ^ {0 + 1} - (3 * (-5))

(4y - 3) (2y ^ 2 + 3y - 5) = 8y ^ 3 + 12y ^ 2-20y ^ 1-6y ^ 2-9y ^ 1 - (- 15)

(4y - 3) (2y ^ 2 + 3y - 5) = 8y ^ 3 + (12-6) y^ 2 + (- 20-9)y - (-15)

Taking into account that equal signs are added and the same sign is placed, and that - * - = +we have:

(4y - 3) (2y ^ 2 + 3y - 5) = 8y ^ 3 + 6y ^ 2-29y + 15

So,(4y - 3) (2y ^ 2 + 3y - 5) = 8y ^ 3 + 6y ^ 2-29y + 15

Answer:

Option D

Scientists found the wreck of the titanic 3797 m below sea level. How many km below sea level is the wreck?
WINSTONCH [101]

We are given that the titanic is found 3,797 m below sea level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one decimal.

We should take note that the letter k in km means kilo and a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000 m. So to convert, simply multiply a value with unit m with this conversion factor. Conversion factor = 1 km / 1000 m

Depth of titanic = 3,797 m (1 km / 1000 m)

Depth of titanic = 3.797 km = 3.8 km
