The new polynomial identity is 2(x² + 2xy + y²)

Given,

The polynomial identities

Column A Column B

(x − y) (x2 + 2xy + y2)

(x + y) (x2 − 2xy + y2)

(y + x) (ax + b)

(y − x) (cy + d)

We have to square an identity from column A and add it with any one identity from column B.

So,

Lets take (x + y)

(x + y)² = x² + 2xy + y²

We can add this identity with x² + 2xy + y² in column B.

That is,

x² + 2xy + y² + x² + 2xy + y²

= 2x² + 4xy +2 y²

= 2(x² + 2xy + y²)

That is,

The new polynomial identity is 2(x² + 2xy + y²)

Is the function even, odd or neither?<br> y=x^2-2x-8

mestny [16]

It is neither.

To be even, f(x) must equal f(-x).

If you substitute -x for x, you'd get

y = (-x)^2 - 2(-x) -8

y = x^2 +2x -8

This is not the same as the original, so this is not even.

To be odd, f(x) must equal -f(-x).

If you take the -x substitution from the last step and then multiply it by -1, you'd have:

y = -1 (x^2 +2x -8)

y = -x^2 -2x +8

This is not the same as the original either.

The function is neither even nor odd.

I need to know the answer and how to solve this

AURORKA [14]

Answer:

135

Step-by-step explanation:

subtract 180 by 45 since a line is 180, that is what you get for the angle that is adjacent to angle 2, there is a rule if it is adjacent, they equal each other. thus, angle 2 is 135

Answer: $\boxed{\bold{x=-7}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Subtract 12 From Both Sides

$\bold{11x+12-12=8x-9-12}$

[ Step Two ] Simplify

$\bold{11x=8x-21}$

[ Step Three ] Subtract 8x From Both Sides

$\bold{11x-8x=8x-21-8x}$

[ Step Four ] Simplify

$\bold{3x=-21}$

[ Step Five ] Divide Both Sides By 3

$\bold{\frac{3x}{3}=\frac{-21}{3}}$

[ Step Six ] Simplify

$\bold{x=-7}$

A-4/5 = 12 what is a and show the work

topjm [15]

Solving $a-\frac{4}{5}=12$ we get $a=\frac{64}{5}$

Step-by-step explanation:

We need to find the value of a. We are given:

$a-\frac{4}{5}=12$

Solving:

$a-\frac{4}{5}=12\\Add\,\,\frac{4}{5}\,\,on\,\,both\,\,sides:\\a-\frac{4}{5}+\frac{4}{5}=12+\frac{4}{5}\\a=12+\frac{4}{5}\\Taking\,\,LCM:\\a=\frac{12*5+4}{5}\\a=\frac{60+4}{5}\\a=\frac{64}{5}$

So, Solving $a-\frac{4}{5}=12$ we get $a=\frac{64}{5}$
