If we pay $8.28 for 18 stamps we can find the price of one stamp by dividing by 18.

So, the price of one stamp will be
$8.28 / 18 = $ 0.46

To find the price of 12 stamps we have to multiply by 12 and finally find
$0.46 * 12 = $5.52

Hence, the cost of 12 stamps is $5.52

What is the value of x?
diamong [38]

Using a theorem (yes i forgot the name of the theorem), we know that because the angles opposite of the sides are congruent, the sides must be congruent aswell. Therefore:

3x - 24 = x + 10

Now solve, starting by using the addition and subtraction properties of equality:

3x - 24 + 24 = x + 10 + 24

3x  = x + 34

3x - x = x - x + 34

2x = 34

Now, use the division property of equality:

(2x)/2 = (34)/2

x = 17

Therefore, x = 17.

<em>Hope this helps! :)</em>

The area of a square is (4x + 3)^2 square inches. The perimeter of the square is 172 inches. What is the value of x?
stepan [7]

Answer:

x = 10

Step-by-step explanation:

the area of a square = s² ( s is the side length )

s² = (4x + 3)² ( take the square root of both sides )

s = \sqrt{(4x+3)^2} = 4x + 3

perimeter = 4s = 172, that is

4(4x + 3) = 172 ( distribute left side )

16x + 12 = 172 ( subtract 12 from both sides )

16x = 160 ( divide both sides by 16 )

x = 10

Use De Moivre's theorem to write the complex number in trigonometric form: (cos(3pi/12) + i sin (3pi/12))^5
Jet001 [13]
\boxed{\text{De Moivre's Theorem: } (cos\theta + isin\theta )^{n} = cosn\theta + isin(n\theta )}

(cos\frac{3\pi}{12} + isin\frac{3\pi}{12})^{5} = cos\frac{5 \cdot 3\pi}{12} + isin\frac{5 \cdot 3\pi}{12}
= cos\frac{15\pi}{12} + isin\frac{15\pi}{12} \text{ or (A)}
