Answer:
Step-by-step explanation:
If you want to factor this, you have to use the quadratic formula to do so.
For us, it looks like this:
which simplifies to
Since it breaks every mathematical rule to have a negative number under an even index radical, we have to deal with that using the imaginary "i". You should know at this point that 
so we will do a rewrite on that equation above:
which simplifies further to
This is the answer but we can separate it into its proper standard form which is
and 
The equation would be 35=5x. ‘x’ is the number of seashells her brother has, and the 5 in front of the x is showing that she has 5 times more than him. to find how many her brother has, divide both sides of the equation by 5 to make the x stand alone. you should then get 7=x, meaning that her brother has 7 shells
For this case we have that by definition of trigonometric relations of a rectangular triangle, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. While the tangent of the same angle is given by the leg opposite the angle on the leg adjacent to the angle.
Then, according to the figure we have:
