Answer:

Cara is correct because there is a no fixed answer sign for the cara's answer and by probability you will observe that cara isnt sure that her answer is + or - but most probably the sign of her answer is positive but not surely so it is plus minus 17

Eva8 [605]

Answer:

= -√6

Step-by-step explanation:

1) collect like terms by subtracting coefficients:

3√6 - 4√6

(3-4)√6

2) calculate (3-4):

(3-4)√6

-1√6

3) the coefficient of -1 does not have to be written, but the negative sign remains:

-1√6

-√6

so therefore:

-√6 is your answer

Calculer x si (x+1/2)^2= 4/9

-Dominant- [34]

Answer:

$x=-\frac{7}{6}\\x=\frac{1}{6}$

Step-by-step explanation:

The equation to solve is:

$(x+\frac{1}{2})^2=\frac{4}{9}$

To get rid of the "square", we need to take square root of both sides:

$\sqrt{(x+\frac{1}{2})^2}=\sqrt{\frac{4}{9}}\\x+\frac{1}{2}=\frac{\sqrt{4}}{\sqrt{9}}$

Then we use algebra to find the value(s) of x. Remember, when we take square root, we have to add up a "+-" (on the right side). Shown below:

$x+\frac{1}{2}=+-\frac{\sqrt{4}}{\sqrt{9}}\\x+\frac{1}{2}=+-\frac{2}{3}\\x=\frac{2}{3}-\frac{1}{2}=\frac{1}{6}\\x=-\frac{2}{3}-\frac{1}{2}=-\frac{7}{6}$

So these are 2 answers for x.
