Answer:
A. x-6
Step-by-step explanation:
Maybe you want to simplify ...
((6x)/(10x^2))/(6/(10x^3 -60x^2))
Invert and multiply. Cancel common factors from numerator and denominator.

Answer:
a.
.
b. The axis of symmetry for
is
.
Step-by-step explanation:
a. The vertex form of a quadratic is given by
, where (h, k) is the vertex.
To convert from
form to vertex form you use the process of completing the square.
Step 1: Write
in the form
. Add and subtract 4:

Step 2: Complete the square 

b. The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.
For a quadratic function in standard form,
, the axis of symmetry is
.
The axis of symmetry for
is
.
Look at the graph shown below.
Answer: -8i
Explanation: Simplify the real and imaginary parts of that expression step by step to be left with -8i
Hope this helps!
The answer is: width = t - 9
A = l * w
A = t² - 4t - 45
l = t + 5
t² - 4t - 45 = (t + 5)w
