The length of a rectangle is five feet less than

Mathematics
1 answer:
kotegsom [21]3 years ago
3 0

Answer:

Length is w-5

Area  = length x width

84 = (w-5)w

84 = w^2 - 5w

0 = w^2 - 5w - 84

0 = (  w     -    12 )( w   +     7    )

w + 7 = 0 leads to negative measures.

w-12=0 ---> w = 12

width is 12, length is 5 less, or 7

M–[(m–n)÷(−2)](−5), if m=−4, n=−6
jeka94

Answer:

-9

Step-by-step explanation:

We are given the expression m–[(m–n)÷(−2)](−5).  Substituting -4 for m and -6 for n, we get:

-4–[(-4 + 6)÷(−2)](−5)

We must do the work that appears inside parentheses first:

-4–[(  2  )÷(−2)](−5)

Next we must do the work that appears inside square brackets:

-4–[     -1    ](−5)

                                             Multiplication comes next.  The above expression becomes:

-4 - [ 5  ]

which in turn comes out to -9

How many shapes are in the world
Montano1993 [528]
There are an infinite number of shapes, because a shape can have any number of sides. This is where we get into our laws of fractals. A fractal is a shape with an infinite perimeter and area, meaning that every level of infinity is another shape, but can be beat by another shape. However, this is all philosophical math and goes way beyond the context of your question.

To keep it short and simple, there are an infinite number of shapes in the world.
