Arectangular room measures 14 feet by 10 feet. find the cost of installing a strip of wallpaper around the room if the wallpaper costs $0.72 per foot.

The cost of installing a strip of wallpaper around the room would be $100.80

Step-by-step explanation:

1. The formula for a rectangle's area is A = l x w. The "l" means length and the "w" means width. 14 is the length and 10 is the width, so that should leave you with A = 14 x 10.

2. When you multiply 14 by 10, you should get A = 140.

3. Since wallpaper costs $0.72 per foot, all you want to do is multiply 140 by $0.72 and you should end up with $100.80 as a result.

If this answer is late or incorrect I deeply apologize!

I hope my answer is helpful :)

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
