The area of a square bedroom is 144 square feet. what is the length of one wall?
Rufina [12.5K]
The answer is:  "12 feet" .
________________________________
Note:  In a square, the length of EACH of the four sides of the square is the same.

Area = Length * width. 

For a square, length = width.

So for a square, Area = length * width = (length of a side)² = s² ,

Given:  A = s² = 144 ft² ;

Solve for the positive value of "s" .
________________________________
  →  s² = 144 ft² ;  Take the "square root" of each side ;

  → √(s²) = √(144 ft²) ;

  →   s = 12 ft.
_______________________________
The answer is:  12 ft.

Can someone please help me with this math problem:)
Dennis_Churaev [7]

Answer:

x = 20

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{x}{12} = \frac{15}{9} ( cross- multiply )

9x = 180 ( divide both sides by 9 )

x = 20

Simplify the expression 4(x − 5)(x2 + x + 2).
N76 [4]

Answer:

  4x^3 − 16x^2 − 12x − 40

Step-by-step explanation:

= 4(x)(x^2 +x +2) +4(-5)(x^2 +x +2) . . . use the distributive property

= 4x^3 +4x^2 +8x -20x^2 -20x -40 . . . . and again

= 4x^3 -16x^2 -12x -40
