The track is a square with half circle on its right and left side. The area of the square is 128 feet². The length is 22.6 feet

<h3>How to illustrate the information?</h3>

It should be noted that the area of the square will be:

= x².

Therefore, 128 = x².

x ,= ✓128

x = 11.3

Therefore the radius of the circle will be:

= 11.3/2

= 5.65

The length of the truck will be:

= 11.3 + 5.65 + 5.65

= 22.6

The length is 22.6 feet

Jim, Carla and Tomy are members of the same family. Carla is 5 years older than Jim. Tomy is 6 years older than Carla. The sum o
Blizzard [7]

We are given these three people age below:

  • Jim's age
  • Carla's age
  • Tomy's age

We define the age of Jim as any variable, because the problem doesn't give any specific age. I will define Jim's age as x.

  • Jim's age = x

Next, Carla is 5 years older than Jim. That means if Carla is 5 years older, her age would be x+5.

  • Carla's age = x+5

Then Tomy is 6 years older than Carla. That means the age would be 6+(x+5).

  • Tomy's age = 6+(x+5)

The sum of their three ages is 31 years old. That means we add all these ages and equal to 31.

\large{x + x + 5 + 6 + x + 5 = 31}

Combine like terms and solve for x.

\large{3x + 16 = 31}  \\  \large{3x = 31 - 16} \\  \large{3x = 15} \\  \large{x = 5}

Then we substitute the value of x in ages to find these three people ages.

  • Jim's age = x = 5
  • Carla's age = x+5 = 5+5 = 10
  • Tomy's age = 6+(x+5) = 6+(5+5) = 6+10 = 16.

Answer

  • Jim's age = 5
  • Carla's age = 10
  • Tomy's age = 16

elena-s [515]

Answer:

x2 - 10x - 1994

Step-by-step explanation:

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  x2-10x-1994

The first term is,  x2  its coefficient is  1 .

The middle term is,  -10x  its coefficient is  -10 .

The last term, "the constant", is  -1994

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1994 = -1994

Step-2 : Find two factors of  -1994  whose sum equals the coefficient of the middle term, which is   -10 .

     -1994    +    1    =    -1993

     -997    +    2    =    -995

     -2    +    997    =    995

     -1    +    1994    =    1993

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 x2 - 10x - 1994
