This MIGHT be the answer, I am 99% sure!
we have

This is a mixed number
we know that
A mixed number is a combination of a whole number and a fraction.
So
is equal to

where
is the whole number
is the fraction

therefore
the answer is

Considering the definition of zeros of a function, the zeros of the quadratic function f(x) = x² + 4x +9 do not exist.
<h3>Zeros of a function</h3>
The points where a polynomial function crosses the axis of the independent term (x) represent the so-called zeros of the function.
In summary, the roots or zeros of the quadratic function are those values of x for which the expression is equal to 0. Graphically, the roots correspond to the abscissa of the points where the parabola intersects the x-axis.
In a quadratic function that has the form:
f(x)= ax² + bx + c
the zeros or roots are calculated by:

<h3>This case</h3>
The quadratic function is f(x) = x² + 4x +9
Being:
the zeros or roots are calculated as:



and



If the content of the root is negative, the root will have no solution within the set of real numbers. Then
has no solution.
Finally, the zeros of the quadratic function f(x) = x² + 4x +9 do not exist.

Answer:
60 books
Step-by-step explanation:
let the number of books Willy has be x , then
Tammy has 4x books
Willy has 180 fewer books , that is Tammy has 180 more than Willy , so
4x = x + 180 ( subtract x from both sides )
3x = 180 ( divide both sides by 3 )
x = 60
Thus
Willy has 60 books andTammy has 4 × 60 = 240 books
which is 180 more than Willy
