Answer: 0.5

Step-by-step explanation:

There are 13 hearts. The chance of drawing a heart in your first draw is 13/52, or in other words 1/4

There are 13 diamonds. The chance of drawing a diamond on your second draw is 13/52, or in other words, 1/4

The chance of drawing a heart, replacing it, drawing a diamond, are 1/4*1/4=1/2.

Solve x^2 + 4x + 8 = 0

Mkey [24]

Answer:

x = -2 + 2 i or x = -2 - 2 i

Step-by-step explanation:

Solve for x:

x^2 + 4 x + 8 = 0

Subtract 8 from both sides:

x^2 + 4 x = -8

Add 4 to both sides:

x^2 + 4 x + 4 = -4

Write the left hand side as a square:

(x + 2)^2 = -4

Take the square root of both sides:

x + 2 = 2 i or x + 2 = -2 i

Subtract 2 from both sides:

x = -2 + 2 i or x + 2 = -2 i

Subtract 2 from both sides:

Answer: x = -2 + 2 i or x = -2 - 2 i

Answer:

$\large \boxed{\text{There is no solution}}$

Step-by-step explanation:

$\begin{array}{rcll}3x - 4 + 1 & = & -2x - 5 + 5x & \\3x - 3 & = & 3x - 5 & \text{Combined like terms on each side}\\-3 & = & -5 & \text{Subtracted 3x from each side}\\\end{array}\\\text{This is impossible. There is $\large \boxed{\textbf{no solution}}$ to the equation.}$
