Which of the following shows why the commutative property doesn't work under subtraction

Hello!  To answer your question, you first need to know what the commutative property is and does.  Down to the basics, it lets you switch around numbers and it would allow me to say that 2+5=7 and 5+2=7.  This property also works in multiplication, because if I take 4*2=8, and 2*4 still equals 8.  Now that I've either refreshed or hopefully helped you to understand the property better, why wouldn't it work under subtraction?  If you switch numbers around in subtraction, will your answer still be the same?  Once you answer that, take a peak at the worksheet!  I hope this has helped in some way, and if you have any further questions send me a question or another message.  Good luck :)

Answer with explanation:

Commutative property under subtraction:

If a and b are any two real numbers such that,⇒ a-b =b-a, then we say that ,a and b Satisfy Commutative property under Subtraction.

Take any two real numbers

a=5.6

And,b=7

→a-b

=5.6-7

= -1.4

→b-a

=7-5.6

=1.4

So,a-b≠b-a

Therefore  , we can say that, real numbers doesn't satisfy commutative property under subtraction.

Option D: ⇒5-1≠1-5

This statement shows that, commutative property doesn't work under subtraction.

The height of the triangle is 3 meters longer than twice its base. Find the base and height if the area is 8 square meters. Roun
polet [3.4K]

9514 1404 393

Answer:

  • base: 2.18 m
  • height: 7.35 m

Step-by-step explanation:

Let b represent the base of the triangle in meters. Then the height is ...

  h = 3 +2b

and the area is ...

  A = 1/2bh

  8 = 1/2(b)(3 +2b)

  16 = 3b +2b^2 . . . . . . . multiply by 2 and eliminate parentheses

  2(b^2 +3/2b + (9/16)) = 16 + 9/8 . . . . . . complete the square

  2(b +3/4)^2 = 17.125

  (b +3/4)^2 = 8.5625 . . . . . divide by 2

  b + 0.75 = √8.5625 ≈ 2.9262

  b = -0.75 +2.9262 = 2.1762

  h = 3 +2b = 7.3523

The base is about 2.18 meters and the height is about 7.35 meters.
