c(x) = 4x - 2

d(x) = x^2 + 5x

4x - 2(x^2 + 5x)

Using FOIL, distribute each term appropriately.

4x^3 + 20x^2 - 2x^2 - 10x

Combine like terms.

4x^3 + 18x^2 - 10x is the simplified polynomials achieved when c(x) and d(x) are multiplied.

solniwko [45]

Answer:

10, -5, -11

Step-by-step explanation:

f(x) = - 3x-5

f(-5) = -3(-5) - 5 => 15 - 5 => 10

f(0) = -3(0) - 5 => 0 - 5 => -5

f(2) = -3(2) - 5 => -6 - 5 => -11

Rachel plays a game by rolling two number cubes with sides numbered 1 through 6 to win the game the sum of the numbers facing up

Artist 52 [7]

The probability that Rachel will win the game is: 1/12

Step-by-step explanation:

The number cubes has six sides numbered between 1 to 6. the chances of each number are equally likely

Let S be the sample space

The sample space has 6*6 = 36 outcomes.

Now, Let A be the event that the sum of numbers on both number cubes is 10

A = {(4,6),(5,5), (6,4)

n(A) = 3

$P(A)= \frac{n(A)}{n(S)}\\=\frac{3}{36}\\=\frac{1}{12}$

The probability that Rachel will win the game is: 1/12
