Answer:

$\frac{29a-24}{5(a-3)}$

Step-by-step explanation:

Thinking process:

The problem is an addition one with directed signs, therefore:

$4 + \frac{a}{a-3} + \frac{4}{5}$

the lowest common denominator is the product of 5 and (a - 3)

This gives:

$\frac{4*5(a-3)+a(5)+4(a-3)}{5(a-3)}$

solving and opening parentheses:

$\frac{20a-12+5a+4a-12}{5(a-3)}\\= \frac{29a-24}{5(a-3)}$

Tyler needs to get the windows in his new home cleaned. The cleaning company needs to know the total number of window panes befo

andrew-mc [135]

Answer:

There are 192 window panes in total.

Step-by-step explanation:

Since each window has four window panes across and four window panes down,the number of panes per window is:

$w=4*4=4^2$

The total number of window panes in 'n' windows is:

$P=n*4^2$

With n = 12 windows, the expression that describes the total number of window panes is:

$P=12*4^2\\P=192\ panes$

There are 192 window panes in total.
