Step-by-step explanation:

2(7x +8)=12

2(7x +8)/2 =12/2

7x +8 =6

7x=6-8

7x = -2

x= -2/7

Hi there! :)

12=2(7x+8)

Use the Distributive property:

12=14x+16

Move all the numbers to the right side and the variables to the left side:

-14x=16-12

-14x=4

Divide both sides by -14 to isolate x:

x=-\frac{4}{14} \\-\frac{2}{7}

<h2>Therefore, x=-\frac{2}{7}</h2>

Hope this helps you!

A perfect square trinomial can be represented by a square model with equivalent length and width. Which polynomial can be repres
lina2011 [118]
The correct answer is 
A) x^2 - 6x + 9

In fact, this is a trinomial of the form ax^2-bx+c, whose solutions are given by
x_{1,2}=  \frac{-b\pm \sqrt{b^2 -4ac} }{2a}
Using this formula for the trinomial of the problem, we find:
x1,2=  \frac{6 \pm \sqrt{6^2-4\cdot 1\cdot 9}}{2} =3
<span>we see that this trinomial has two coincident solutions (x=3 with multiplicity 2). This means that it can be rewritten as a perfect square, in the following form: 
</span>(x-3)^2<span>
