7. If each sister has one brother, it would be one brother total, because they are all related. They don't each have their own brother. So mom+dad+sisters(4)+brother=7 total.

hope this helped :)

Using the quadratic formula to solve x2 = 5 – x, what are the values of x?
MrMuchimi

Answer:

A quadratic equation ax^2+bx+c = 0    ....[1] where, a, b and c are coefficient.

Then the solution is given by:

x = -\frac{b \pm \sqrt{b^2-4ac}}{2a}        ....[2]

As per the statement:

Given the equation:

x^2=5-x

⇒x^2+x-5 = 0

On comparing with [1] we have;

a =1, b = 1 and c = -5

Then substitute these in [2] we have;

x = \frac{-1 \pm \sqrt{1^2-4(1)(-5)}}{2(1)} =\frac{-1 \pm \sqrt{1+20}}{2} =\frac{-1 \pm \sqrt{21}}{2}

Therefore, the values of x are:

x = \frac{-1 + \sqrt{21}}{2} , \frac{-1 - \sqrt{21}}{2}
