The width of a rectangle is 6 m shorter than its length. If the perimeter of the rectangle is 52 m, find its length and width.
sineoko [7]

Answer:

Length = 16 m , width = 10 m

Step-by-step explanation:

Let the Length of the rectangle be L meters.

Now, Width of the rectangle is (L-6) m.

Perimeter of the Rectangle = 52 m

Now, we know that

Perimeter of the Rectangle =  2(L+W)

⇒ 2(L+W) =  52 m

or, 2(L + (L-6)) = 52 m

Simplifying, we get 2L + 2L -12 = 52

or, 4L = 64

or, L = 16 m

So, width = L- 6 = (16-6) m = 10 m

So, length = 16 m

and width = 10 m

Four more than three times n equals -5
Verizon [17]
3n+4=-5

do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.

-5-4=-9

since 4-4=0, we can take 4 out of the equation. now you have:

3n=-9

now divide -9 by 3

-9/3=-3

n=-3

hope this helps :)
