Number 1:

9x^2 + 12x + 4 -> (3x + 2)^2
16x^2 + 24x + 9 -> (4x + 3)^2

2. x^2 + Bx + 64
B = (sqrt64) *2 = 16

3.
Solving equations like this requires completing the square, which has the first step of choice 4.

Match the expressions to their solutions or equivalents. Solution of 0.5 x = 0

rodikova [14]

$\huge\text{Hey there!}$

$\huge\textbf{Assuming that your expression is:}$

$\textsf{0.5x = 0}$

$\huge\textbf{If so, let's solve for the given expression:}$

$\textsf{0.5x = 0}$

$\huge\textbf{Divide 0.5 to both of the sides you have:}$

$\mathsf{\dfrac{0.5x}{0.5} = \dfrac{0}{0.5}}$

$\huge\textbf{You have to simplify the equation above:}$

$\mathsf{x = \dfrac{0}{0.5}}$

$\mathsf{x = 0}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{x = }\frak{0}}\huge\checkmark$

Suppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards

lubasha [3.4K]

Answer:

The expected value of the wager is $1.77

Step-by-step explanation:

Firstly, we need to calculate the probability that both are hearts

In a standard deck of cards, we have 13 cards in the heart suite

Thus the probability that both cards are hearts without replacement = 13/52 * 12/51 = 1/17

Now the probability that at least one is a heart = 1 - probability that both are hearts = 1 -1/17 = 16/17

Thus, the expected value of the wager = 606(1/17) - 36(16/17) = 35.65-33.88 = $1.77

The expected value of the wager = $1.77
