The evolution of mathematics might be seen as an ever-increasing series of abstractions, or alternatively an expansion of subject matter. The first abstraction, which is shared by many animals, was probably that of numbers: the realization that a collection of two apples and a collection of two oranges (for example) have something in common, namely quantity of their members.
In addition to recognizing how to count physical objects, prehistoric peoples also recognized how to count abstract quantities, like time - days, seasons, years.Elementary arithmetic (addition, subtraction, multiplication and division) naturally followed.

If x+y=10 and x-y =6 what is the answer of x cube - y cube fast

AfilCa [17]

Answer:

x+y=10 which means that x=10-y

Replace 10-y in the other equation which gives you:

10-y-y=6

10-2y=6

-2y=-4

y=2

Replace 2 in any of the 2 equations same answer for both:

x+y=10

x+2=10

x=8

So,

${x}^{3} - y^{3}$

$= {8}^{3} - {2}^{3}$

=512-8

=504

Hope this helps!

Naomi has been contracted to put decorative lights on the outside edges of a building. She knows that each string of lights she

Lady_Fox [76]

You would divide 1350 by 47 to find our how many strings of lights she would need.

1350 / 47 = 28.7234

note that IF you choose 28, you would run short because it would not be enough to cover all of that edge.

so you would need to round up to 29

therefore our answer would be D)29 strings of lights.
