Find the value of x?​
Arisa [49]

Answer:

x = 5

Step-by-step explanation:

x + 5 = \frac{1}{2}(x^{2} - x)    {Midpoint theorem}

2(x+ 5) = x² - x

2x + 10 = x² - x

x² - x - 2x - 10 = 0

x² - 3x - 10 = 0

x² - 5x + 2x - (5*2) = 0

x(x - 5) + 2(x - 5) = 0

(x -5)(x + 2) = 0

{x + 2 is ignored because measurement could not be in negative value}

x - 5 = 0

x = 5

IrinaVladis [17]

Answer:

Mr Park has enough money to pay his rent.

Step-by-step explanation:

The amount of the monthly rent paid  = $1000

The account balance after depositing the paycheck = $1441.33

A carpenter wants to expand a square room. The new room will have one side 4 feet longer and the adjacent side 6 feet longer tha
gogolik [260]

Answer:

  Dimensions of original room = 12 x 12 feet.

Explanation:

 Let the size of old square room be a x a.

 New dimension = ( a+4 ) x ( a + 6 )

   We have area of the new room will be 144 square feet greater than the area of the original room.

  So,     ( a+4 ) x ( a + 6 ) = a x a + 144

              a²+10a+24= a²+144

              10a = 120

                  a = 12 feet.

 Dimensions of original room = 12 x 12 feet.
