Answer:
20
Step-by-step explanation:
Given :
Length = l
Width = w
Area of square = 45
Let side of square = x
Area of square = x²
45 = x²
√45 = x
l of rectangle = x + 5 = √45 + 5
w of rectangle = x -5 = √45 -5
Area of rectangle= l * w
Area = (√45 + 5) * (√45 - 5)
Area = 45 - 5√45 + 5√45 -25
Area = 45 -25
Area of rectangle = 20
Subtract 2 from both sides
3x+2-2=5-2
3x=3
Divide both sides by 3
3x/3= 3/3
The answer is ×=1
Answer:
The statement 'A quadratic function with real coefficients has real roots' is some times true and some times false.
Step-by-step explanation:
The quadratic function in the form ax² + bx + c = 0, has real roots when the discriminant, given by D = b² - 4ac is greater than or equal to zero.
And the equation has imaginary roots when D = b² - 4ac is less than zero.
So, even a quadratic equation has real coefficients can have non-real roots depending on the value of the discriminant.
Hence, the statement 'A quadratic function with real coefficients has real roots' is some times true and some times false. (Answer)
