Answer:
x = 3.5
Step-by-step explanation:
By definition, congruent chords are equidistant from the center of a circle. We are given two congruent chords and their distances(the lines perpendicular), meaning those distances must be equal. We set set up an equation to model the situation:
x + 8 = 3x + 1
8 = 2x + 1
2x = 7
x = 3.5
You foil for this one so it means that you multiply -3 with g, then multiply -3 with -f, you should get -3g+3f, but i'm not sure if i did it correctly if i did get it wrong then my bad
