Answer:
The answer to your question is 10 dm
Step-by-step explanation:
Data
length of a rectangle = x + 4
height of a rectangle = x - 6
Area of the rectangle = 56 dm²
length of the square = x
Process
1.- Find x with the information given for the rectangle
Area = length x height
Substitution
56 = (x + 4)(x - 6)
Expand
56 = x² - 2x - 24
Equal to zero
x² - 2x - 24 - 56 = 0
Simplify
x² - 2x - 80 = 0
Factor
(x - 10)(x + 8) = 0
Equal to zero
x₁ -10 = 0 x₂ + 8 = 0
x₁ = 10 x₂ = -8
2.- Conclusion
The length of the square is 10 dm because there are no negative lengths.
Answer:
length 5cm, width 4cm, door width 2/5cm or. 4cm, length 10 ft, width 7.5 ft
D is correct <3 hope it helped!
Answer:
4.05 meters or 405 cm
Step-by-step explanation:
The equation to use is
(x - 330) x 5 = x - 30
330 is equal to 3.30 meters.
Then solve the equation.
(X - 330) x 5 = x - 30
5x - 1650 = x - 30
-x
4x - 1650 = -30
+1650 + 1650
4x = 1620
/4 /4
X = 405cm
