Well
1/3-1/4=1/12
so 1/3=1/12+1/4=1/12+3/12=4/12
and 1/4=-(1/12-1/3)=-1/12+1/3=-1/12+4/12=3/12
4/12+3/12=7/12

For what values of a are the following expressions true?/a+5/=-5-a

katovenus [111]

Explanation:

The expression is given below as

$|a+5|=-5-a$

Concept:

We will apply the bsolute rule below

$\begin{gathered} if|u|=a,a>0 \\ then,u=a,u=-a \end{gathered}$

By applying the concept, we will have

$\begin{gathered} \lvert a+5\rvert=-5-a \\ a+5=-5-a,a+5=5+a \\ a+a=-5-5,a-a=5-5 \\ 2a=-10,0=0 \\ \frac{2a}{2}=\frac{-10}{2},0=0 \\ a=-5,0=0 \end{gathered}$

Hence,

The final answer is

$a\leq-5$

(4x2 – 6x + 2) + (-5x2 + 6x – 6)

lys-0071 [83]

$(4*2-6x+2)+(-5x2+6x-6)$
$8-6x+2+(-5)*2+6x-6$
$8-6x+2-10+6x-6$
$\not 10-6x-\not10+6x-6$
$-6x+6x-6$
$-6$
The answer is: -6
