Mathematics

Answer:

  3 < x < 27

Step-by-step explanation:

We can't tell what "must ne greater" means, so we'll tell you the limits on the side length and you can choose the one that is relevant.

The third side of a triangle must have a length that lies between the difference and sum of the two lengths you know.

 15 -12 = 3

  15 +12 = 27

The value of x must be between 3 and 27:

  3 < x < 27

__

If you allow the triangle to have zero area, then x can be 3 or 27. Many authors claim such a "triangle" is not allowed, so don't allow those cases.

The circumference of the hub cap of a tire is 83.21 centimeters. Find the area of this hub cap. Use
Elena L [17]

Answer:

<u>551 square centimeters</u>

Step-by-step explanation:

Finding the radius (r) :

  • C = 2πr
  • 83.21 = 2 x 3.14 x r
  • 83.21 = 6.28r
  • r = 83.21/6.28
  • r = 13.25 cm

Finding the area :

  • A = πr²
  • A = 3.14 x (13.25)²
  • A = 3.14 x 175.5625
  • A = <u>551 square centimeters</u> (nearest whole number)

<u></u>

The area of this hub cap is about <u>551 square centimeters</u>.

What's the awnser for this ×+5=-3×+25
lord [1]

Answer:

x=5

Step-by-step explanation:

x+5 = -3x+25

Add 3x to each side

x+3x+5 = -3x+3x+25

4x +5 = 25

Subtract 5 from each side

4x+5-5 = 25-5

4x = 20

Divide each side by 4

4x/4 = 20/4

x =5
