Answer:

x= 7

Step-by-step explanation:

The equation is 8+4= 2(x-1)

Distribute into the parenthesis.

8+4= 2x-2

Now, add.

12= 2x-2

Add 2 to both sides.

12= 2x-2

+2 +2

Then, divide by 2 to both sides to isolate the variable.

2 2

x=7

Which expression represents the polynomial −2x^2−4x^4+8x+x^5−2x^3 rewritten in descending order?

tigry1 [53]

The polynomial $-2x^2-4x^4+8x+x^5-2x^3$ arranged in descending order is $x^5-4x^4-2x^3-2x^2+8x$

Step-by-step explanation:

We need to rewrite the polynomial $-2x^2-4x^4+8x+x^5-2x^3$ in descending order.

For writing the polynomial in descending order we arrange the exponents of variables from largest exponent to the smallest exponent.

The given polynomial is:

$-2x^2-4x^4+8x+x^5-2x^3$

The descending order of the polynomial is:

$x^5-4x^4-2x^3-2x^2+8x$

So, the polynomial $-2x^2-4x^4+8x+x^5-2x^3$ arranged in descending order is $x^5-4x^4-2x^3-2x^2+8x$
