(X + 3)( x + 4) = 5 is the correct answer

Answer:

The quadratic equation is (x + 3)(x + 4) = 5

Step-by-step explanation:

If the degree of a polynomial is two then the polynomial is known as a quadratic.

Now, in the given equations we see which polynomial has a degree 2.

Simplify the first equation

x(x^2+1)=0\\x^3+x=0

Degree is 3 and hence it is not a quadratic.

Take 2nd equation

5(4x+2)=3\\20x+10=3

Degree is 1 and hence it is not a quadratic.

Finally, we simplify the third equation

(x+3)(x+4)=5

Apply FOIL method to simplify the left hand side

x^2+4x+3x+12=5=5

Degree is 2 and hence it is a quadratic equation.

Type of Inequality

The given expression, x <= y denotes the type of inequality where the possible values of x are either less than y or equal to less. The value of x cannot be greater than y in any case.

Firstly, put Derek and Paul's collection together:
1950, 1952, 1908, 1902, 1955, 1954, 1901, 1910, 1929, 1935, 1928, 1930, 1925, 1932, 1933, 1920

1950+1952+1908+1902+1955+1954+ 1901+1910+1929+1935+1928+1930+ 1925+ 1932+1933+1920
=30864
=30864÷16
=1929
∴the mean is 1929.

Median:
1901, 1902, 1908, 1910, 1920, 1925, 1928, 1929, 1930, 1932, 1933, 1935,
1950, 1952, 1954, 1955
1930÷1929
=1.0005184
= Median

Range:
1955-1901
=54
∴the range is 54.
