Question

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

tell him how much the job will cost. There are 12 windows, each with four window panes across and four window panes down. Tyler can find the

total number of window panes by multiplying the number of windows by the number of panes in each window. The total number of window

panes is an expression with a whole number exponent.

Answer 1

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.

Answer 2

Answer:

One window has 4 × 4, or 42, window panes, so 12 windows have 12 × 4^2 window panes.

Step-by-step explanation:

One window has 4 × 4, or 42, window panes, so 12 windows have 12 × 4^2 window panes.
