Answer:

−25x+54−32rx+64r−x^2

Step-by-step explanation:

(−28−32r−x+1)(x−2)

Add −28 and 1 to get −27.

(−27−32r−x)(x−2)

Apply the distributive property by multiplying each term of −27−32r−x by each term of x−2.

−27x+54−32rx+64r−x^2+2x

Combine −27x and 2x to get −25x.

−25x+54−32rx+64r−x^2

Answer:

3x^4 - 13x^3 - x^2 - 11x + 6.

Step-by-step explanation:

x^2-5x+2 x 3x^2 +2x +3

= x^2(3x^2 +2x +3) - 5x(3x^2 +2x +3) + 2(3x^2 +2x +3)

= 3x^4 + 2x^3 + 3x^2 - 15x^3 - 10x^2 - 15x + 6x^2 + 4x + 6

Adding like terms:

= 3x^4 - 13x^3 - x^2 - 11x + 6.

Answer:

$\frac{1}{2} x +x = 2 (x-4)$

Step-by-step explanation:

Suppose number is x

Following equation can be written from question statement

$\frac{1}{2} x +x = 2 (x-4)$

Simplifying it further

$\frac{3}{2} x = 2x-8$

$\frac{3}{2} x -2x=-8$

$\frac{3x-4x}{2}= -8$

$-x= -16\\x=16$
