The cost c (in dollars) of making a square window with a side length of n inches is represented by c=n25+175. a window costs $355. what is the length (in feet) of the window?

Length of window = 3/5 feet

Step-by-step explanation:

Cost of making one window (C) = $ 355

Cost of making a square window with length n inch is C = n(25) + 175

C = 25n + 175

By substituting the value of C and n in above equation:

355 = 25n + 175

25n = 355 - 175

25n = 180

n = 180/25

n = 36/5

Length of a square window in inches = 36/5

Length of a square window in feet =  (∵ 1 inch =  1/12 feet)

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
