Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is
Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
D.
We have been given a radical equation . We are asked to find the equation that results from isolating a radical term and squaring both sides of the equation for the equation.
Add on both sides:
Square both sides:
Using radical rule , we will get:
Using perfect square formula , we will get:
Therefore, option D is the correct choice.
The answer is seventeen

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ BCD is an exterior angle of the triangle, thus
∠ BCD = 50° + 60 = 110° → D
