Which property is shown? 4/5+ -<br> 4/5=0
TEA [102]
This looks like the additive inverse property, because when you add something to its negative counterpart (or its additive inverse), you get 0 as a sum.

Another example would be 2+ (-2) = 0. -2 is the additive inverse for 2.

What is the simplified polynomial and the value
Elanso [62]

The simplified polynomial is; xy(x²y - xy² +1) and; the value when x=-3 and y=2 is; -186

From the polynomial given;

  • x²yxy -xy²xy +xy.

The polynomial can be factorised to yield a simpler form as follows;

  • xy(x²y - xy² +1).

This is so because, xy is a common factor.

The value is therefore;

  • (-3×2)((-3)²2 - (-3×2²) +1)

  • -6(18+12+1)

= -186

Answer:

20 units

Step-by-step explanation:

Since the triangle is equilateral then all 3 sides are equal in length.

Equate any 2 sides and solve for x

4x = 3x + 5 ( subtract 3x from both sides )

x = 5

hence

4x = 4 × 5 = 20

3x + 5 = (3 × 5) + 5 = 15 + 5 = 20

7x - 15 = (7 × 5) - 15 = 35 - 15 = 20

The lengths of the sides are 20 units
