Answer:

$a=-\frac{b}{2x}$

Step-by-step explanation:

The equation of a quadratic function is given as:

ax² + bx + c = 0

where a, b and c are the coefficient in the quadratic equation.

The axis of symmetry of the quadratic equation is given as:

$x=-\frac{b}{2a}$

To get the equation for a, we have to make a the subject of formula:

$x=-\frac{b}{2a}\\\\multiply\ both\ sides\ by \ 2a:\\\\x*2a=-\frac{b}{2a}*2a\\\\2ax=-b\\\\Divide\ through\ by\ 2a\\\\2ax/2a=-b/2a\\\\a=-\frac{b}{2x}$

Answer:

• for x

${ \tt{(4x + 1) + 2(x + 5) = 20}} \\ { \tt{4x + 1 + 2x + 10 = 20}} \\ { \tt{6x + 11 = 20}} \\ { \tt{6x = 20 - 11}} \\{ \tt{6x = 9}} \\{ \boxed { \tt{x = \frac{3}{2} = 1.5 }}}$

• for A:

${ \tt{2x + 4 = A}} \\ { \tt{A = 2( \frac{3}{2}) + 4 }} \\ { \tt{A = 3 + 4}} \\ { \boxed{ \tt{A = 7}}}$
