The length of a rectangular garden is 6 feet longer than its width. The garden's perimeter is 180 feet. Find the length of the g

slavikrds [6]

Perimeter is all sides added up together. So as you don't know a side's length you can put it as x and make an equation.
x + x + x + 6 + x + 6 = 180
4x +12 = 180
4x = 180 - 12
4x = 168
x = 168/4
x = 42
as length is 6 feet longer than width length is equal to 42 + 6 = 48 feet

Which of the following are square roots of —8 + 8i/3? Check all that apply.

8090 [49]

Answer:

Options (2) and (3)

Step-by-step explanation:

Let, $\sqrt{-8+8i\sqrt{3}}=(a+bi)$

$(\sqrt{-8+8i\sqrt{3}})^2=(a+bi)^2$

-8 + 8i√3 = a² + b²i² + 2abi

-8 + 8i√3 = a² - b² + 2abi

By comparing both the sides of the equation,

a² - b² = -8 -------(1)

2ab = 8√3

ab = 4√3 ----------(2)

a = $\frac{4\sqrt{3}}{b}$

By substituting the value of a in equation (1),

$(\frac{4\sqrt{3}}{b})^2-b^2=-8$

$\frac{48}{b^2}-b^2=-8$

48 - b⁴ = -8b²

b⁴ - 8b² - 48 = 0

b⁴ - 12b² + 4b² - 48 = 0

b²(b² - 12) + 4(b² - 12) = 0

(b² + 4)(b² - 12) = 0

b² + 4 = 0 ⇒ b = ±√-4

b = ± 2i

b² - 12 = 0 ⇒ b = ±2√3

Since, a = $\frac{4\sqrt{3}}{b}$

For b = ±2i,

a = $\frac{4\sqrt{3}}{\pm2i}$

= $\pm\frac{2i\sqrt{3}}{(-1)}$

= $\mp 2i\sqrt{3}$

But a is real therefore, a ≠ ±2i√3.

For b = ±2√3

a = $\frac{4\sqrt{3}}{\pm 2\sqrt{3}}$

a = ±2

Therefore, (a + bi) = (2 + 2i√3) and (-2 - 2i√3)

Options (2) and (3) are the correct options.

The line through (6,-6) with slope 1/2 in point-slope form ?

aleksandrvk [35]

Answer: $y + 6 = \frac{1}{2}(x - 6)$

Step-by-step explanation:

Point-slope formula: $y - y1 = m(x - x1)$

Plug in the numbers: $y - -6 = \frac{1}{2}(x-6)$

Clear the double negatives: $y + 6 = \frac{1}{2}(x - 6)$
