Which of the following are solutions to the equation below? x^2-2x-24-0

Mathematics
1 answer:
Dominik [7]3 years ago
4 0

Answer:

x=-4

x=6

Step-by-step explanation:

Lets put to work the well known quadratic equation:

x=\frac{-b+/- \sqrt{b^{2}-4ac } }{2a}

Let us also, remember the given equation: x^2-2x-24=0

Where 'a' would be equals to 1, 'b' equals to -2 and c equals to -24.

The quadratic equations with those values is:

\frac{2 +/- \sqrt{4+96} }{2}

Where we obtain two values.

x1= -4

and x2= 6

Could someone help me on this
allochka39001 [22]

Answer:

13.) 314.2 in²

15.) 181.5 ft²

Step-by-step explanation:

The area of a circle is found using the equation:

A = πr²

In this equation, "π" represents the number pi (3.14....) and "r" represents the radius (half the diameter).

For 13.), you have been given the radius. Thus, you can substitute it into the equation and solve for "A".

A = πr²

A = π(10)²

A = π x (100)

A = 314.2 in²

For 15.), you have been given the diameter. To find the radius, you need to divide this value by 2. Once you find the radius, you can plug it into the equation and simplify like above.

diameter = 15.2 ft
radius = 7.6 ft

A = πr²

A = π(7.6)²

A = π x (57.76)

A = 181.5 ft²

The height of the rectangular cereal box is 40 cm.

<h3>How to find height of a rectangular prism?</h3>

Volume of a rectangular prism = lwh

where

  • l = length
  • w = width
  • h = height

Therefore,

10000 = 25 × 10 × h

10000 = 250h

h = 10000 / 250

h = 40 cm
