Question

What’s the correct answer for this question?

Answer 1

x = 3

Explanation:

Since the chords are congruent then they are equidistant from the centre, thus

PG = GO , substitute values

2(4x - 3) - 8 = 4 + 2x ← distribute and simplify left side

8x - 6 - 8 = 4 + 2x

8x - 14 = 4 + 2x ( subtract 2x from both sides )

6x - 14 = 4 ( add 14 to both sides )

6x = 18 ( divide both sides by 6 )

x = 3

Answer 2

C

Explanation:

PG = GO

2(4x-3)-8=4+2x

8x-6-8=4+2x

8x-14=4+2x

8x-2x=4+14

6x=18

Dividing both sides by 6

x = 3
