Answer:

11+2x

Step-by-step explanation:

You can combine like terms to simplify expressions:

6+5=11

-2x+4x=2x

Solution:

Step-1: Combine like terms.

$6 - 2x + 5 + 4x$

$\rightarrow x(-2 + 4) + (6 + 5)$

Step-2: Simplify.

$\rightarrow x(2) + (11)$

$\rightarrow \bold{2x + 11}$

Hence, the simplified expression is $\bold{2x + 11}.$

The quadratic x^2+440x+440^2 can be written in the form (x+b)^2+c, where b and c are constants. What is c/b?

Sauron [17]

This form (x+b)²+c is a vertex form that can be found by completing square for the equation x²+440x+440².

To complete square we will need to use formula a² +2ab + b² = (a+b)²

 x²+440x+440²,
x² +2*220²x +220² -220² +440² (we added 220² -220², so nothing really changed here).

x² +2*220²x +220² -220² +440² ( here , bold part can be rewritten as (x+220)²)

(x+220)² -220² +440² (calculating bold part)

(x+220)² -220² +440² = (x+220)² + 145200

Now we have x²+440x+440², in the form that we need
x²+440x+440² = (x+220)² + 145200

(x+b)²+c = (x+220)² + 145200,
b=220,
c= 145200

So,
c/b = 145200/220 = 660
c/b = 660/1 (if you need it in a fraction form) or 660.
