The length of a rectangular rug is 18 ft. and the length of its diagonal is 22ft. a). What is the width of the rug to the nearest foot? The width is _
b). What is the perimeter of the rug to the nearest foot? The perimeter is _
c) What is the area of the rug to the nearest square foot? The area is _

a:

13ft.

b:

61ft.

c:

228ft.

Step-by-step explanation:

pythagoras theorem part:

22^2 - 18^2 =160

√160 = 12.649... = 13ft. (rounded )

b:

18 + 18 + 12.649... + 12.649... = 36 + 25.298... = 61.298... = 61ft. (rounded)

c:

12.649... x 18 = 227.683... = 228ft. (rounded)

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

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.
