Answer:
(c) Both equations have the same potential solutions, but equation A might have extraneous solutions.
Step-by-step explanation:
The general approach to solving an equation like either of these is to raise both sides of the equation to a power that will remove the radical. In both cases, the result is a quadratic with roots of x=-4 and x=2.
Of these two potential solutions, x = -4 is an extraneous solution for equation A. Both values of x are solutions for equation B. An appropriate description is ...
Both equations have the same potential solutions, but equation A might have extraneous solutions.

<em>Additional comment</em>
The attached graph shows the equations cast into the form f(x) = 0, so x-intercepts are the solutions to the equation. The radical versions of the equations have only x-intercepts that are actual solutions. The version with the radicals removed is a parabola with two solutions (orange). Only one of those matches the solution to equation A (red). Both match the solutions of equation B (purple).
Answer:
No
Step-by-step explanation:
Replace 0.5 for each x, and 4 for each y, and then solve.
-2y - x = -8.5 - 2x - y = -5
-2(4) - 0.5 = -8.5 - 2(0.5) - 4 = -5
-8 - 0.5 = -8.5 - 1 - 4 = -5
-8.5 = -13 = -5
These numbers are not equal to each other, so the answer is no.

<h2>Length of the other leg, expressed in radical form is
</h2>
Step-by-step explanation:
We have Pythagoras theorem,
Hypotenuse² = Base² + Perpendicular²
Here we have
Hypotenuse = 9
Base = 7
Substituting
9² = 7² + Perpendicular²
Perpendicular² = 81 - 49
Perpendicular² = 32
Length of the other leg, expressed in radical form is
