Two identical metal spheres at 8 °C are put in equal amount of water in two beakers, as shown below.

eduard

Answer:

$\boxed{ \text{The temperature of the water in Beaker A will increase.}}$

Step-by-step explanation:

Heat always flows from a hotter object to a colder one. If heat flows from the sphere to the water, $\boxed{\textbf {the temperature of the water will increase.}}$

A is wrong. If the temperature of the water is greater than 8 °C, heat will flow from the water to the sphere.

B is wrong. If the temperature of the water is lower than 8 °C, heat will flow from the sphere to the water..

D is wrong. If heat flows from the water to the sphere, the temperature of the water will decrease.

What is the product? (x-5)(2x+3x-1)

Firlakuza [10]

I assume the first term of the trinomial is 2x^2, and you left out the exponent.

Multiply each term of the binomial by each term of the trinomial.
Then collect like terms.

$(x - 5)(2x^2 + 3x - 1) =$

$= x * 2x^2 + x * 3x + x * (-1) - 5 * 2x^2 - 5 * 3x - 5 * (-1)$

$= 2x^3 + 3x^2 - x - 10x^2 - 15x + 5$

$= 2x^3 - 7x^2 - 16x + 5$
