What is the missing length??
amid [387]

Answer

The missing length is 10

Step-by-step explanation:

Represent the missing length with x

The sides of the given shape are directly proportional.

Mathematically:

(15 + x) to (12 + 8) and x to 7

Represent as a ratio:

(15 + x) : (12 + 8) = x : 8

15 + x : 20= x : 8

Convert to fraction

\frac{15 + x}{20} = \frac{x}{8}

Cross Multiply:

(15 + x)*8 = 20 * x

120 + 8x = 20x

Collect Like Terms

20x - 8x = 120

12x = 120

Solve for x

x = \frac{120}{10}

x = 10

<em>The length of the missing side is 10</em>

Slav-nsk [51]

Answer:

  1. (√30 - 1, 0)
  2. (-√30 - 1, 0)

Step-by-step explanation:

Making the equation of the parabola :

⇒ y = a(x - h)² + k

⇒ y = (x + 1)² - 17 - 13

⇒ y = (x + 1)² - 30

x-intercepts have y = 0 :

  • 0 = (x + 1)² - 30
  • (x + 1)² = 30

Taking the square root on each side :

  • √(x + 1)² = √30
  • x + 1 = ±√30
  • x = ±√30 - 1

The x-intercepts are :

  1. (√30 - 1, 0)
  2. (-√30 - 1, 0)
