Answer:

The simplified form of the given expression is 6-a.

Step-by-step explanation:

The given expression is

$(3-a)\cdot 2+a$

According to distributive property.

$a\cdot (b+c)=ab+ac$

Use distributive property.

$3(2)-a(2)+a$

$6-2a+a$

Combine like terms.

$6+(-2a+a)$

$6-a$

Therefore the simplified form of the given expression is 6-a.

Which expressions are equivalent to when x0? Check all that apply.

Genrish500 [490]

We have that

$\frac{(x+4)}{3} / \frac{6}{x} = \frac{x*(x+4)}{3*6} \\ \\ = \frac{( x^{2} +4x)}{18}$

therefore

case a)
$\frac{(x+4)}{3} * \frac{x}{6}$
Is equivalent

case b)
$\frac{6}{x} * \frac{(x+4)}{3}$
Is not equivalent

case c)
$\frac{x}{6} * \frac{(x+4)}{3}$
Is equivalent

case d)
$\frac{(2 x^{2} +4x)}{6}$
Is not equivalent

case e)
$\frac{(2 x^{2} +4x)}{18}$
Is equivalent

Hence

the answer is

$\frac{(x+4)}{3} * \frac{x}{6}$

$\frac{x}{6} * \frac{(x+4)}{3}$

$\frac{(2 x^{2} +4x)}{18}$
