The length of a rectangle is 5 cm more than its width. The perimeter is 82 cm. Find the length of the rectangle.
weeeeeb [17]

We will represent the length of the rectangle as l and the width as w.


From this problem, we can say l = w + 5. We can also deduct an equation from the second sentence:

2l + 2w = 82

2(w + 5) + 2w = 82 (from substitution)

2w + 10 + 2w = 82

4w = 72

\boxed{w = 18}


Using this value for w, we can find l:

l = 18 + 5

\boxed{l = 23}


The length of the rectangle is 23 cm and the width of the rectangle is 18 cm.

What is the solution to the equation? 16=(x-2)^2/3
jarptica [38.1K]
2^4 = (x - 2)^(2/3)       Multiply the powers on both sides by 3/2
2^(4*3/2) = (x - 2)^ [(2/3)*(3/2)]
2^6 = (x - 2)^1
2^6 = (x - 2)
but 2^6 = 64
64 = (x - 2)                 Remove the brackets.
64 = x - 2                   Add 2 to both sides.
66 = x
