Which of the following expressions is equivalent to a+(– b)? Select all that apply.

Setler79 [48]

Answer: first option.

Step-by-step explanation:

Given the expression:

$a+(- b)$

You need to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

Then, you know that:

$a+(- b)=a-b$

So, an equivalent expression must have $a$ and $-b$ . Let's check the expressions provided in the options:

$(- b ) + a=-b+a \\\\b + (-a)=b-a \\\\(-a ) + b=-a+b$

You can observe that the equativalent expression is:

$(- b ) + a$

9x² - 12x + 4 <br><br>pls need ans.

kolezko [41]

Step-by-step explanation:

$\tt{9 {x}^{2} - 12x + 4}$

Here, the second order of polynomial ax² + bx + c is factorized and expressed as the product of two linear factors. First, we have to find the two numbers that adds to 12 and if we multiply those numbers , we get 36 ( The two numbers should be 6 and 6 ).

⟶ $\tt{9 {x}^{2} - (6 + 6)x + 4}$

⟶ $\tt{9 {x}^{2} - 6x - 6x + 4}$ { Distribute x through the parentheses )

⟶ $\tt{ \underbrace{9 {x}^{2} - 6x}} \: - \underbrace{6x + 4}$

⟶ $\tt{3x(3x - 2) - 2(3x - 2)}$

⟶ $\tt{(3x - 2)(3x - 2)}$

⟶ $\tt{ {(3x - 2)}^{2} }$

$\pink{ \boxed{ \boxed{ \tt{ Our \: final \: answer : \boxed{ \underline{ \tt{{(3x - 2)}^{2} }}}}}}}$

Hope I helped ! ♡

Can some one tell me what I can write to get a 4 grade plz thx

Phoenix [80]

Greetings!

The first step to solve this equation would be to <em>Add Like Terms. </em>
Since 8x and 1x are both the same variable, you can add them together.
This helps to simplify your equation.
Next, you would add 4 to both sides in order to isolate the variables.
This would result in: $8x=16$

Hope this helps.
