Use FOIL method

(2x - 3)(5x + 6) = 2x*5x + 2x*6 + (-3)*5x + (-3) *6

= 10x² + 12x - 15x - 18 {Combine like terms}

= 10x² - 3x - 18

Like terms are terms that have same variable with same power.

Write a proportion and show work

NeX [460]

for this case we must write a proportion that shows the earnings obtained from Mrs. Miller for the sale of the house.

By making a rule of three we have:

179000 ------------> 100%

x -----------------------> 6%

Where "x" represents the gains obtained.

So:

$x = \frac {6 * 179000} {100}$

Writing the proportion:

$\frac {x} {179000} = \frac {6} {100}$

The earns were:

$x = 10740$

ANswer:

$\frac {x} {179000} = \frac {6} {100}\\x = 10740$
