AB and BC are tangent to circle D. Find x if AB = 2x + 9 and BC = 3x + 6. Find x.
2 answers:
It woulds be x+15 because if you take 2x and subtracted from the 3x then you get x and then you add the 9 and 6 witch you get 15
Answer:
the value of X comes out to be equal to 3
Step-by-step explanation:
since AB and BC are tangent to the circle D
then the length of the tangent will be same
AB will be equal to BC
where,
AB = 2 x + 9
and
BC = 3 x + 6
2 x + 9 = 3 x + 6
3 x - 2 x = 9 - 6
x = 3
hence, the value of X comes out to be equal to 3

Answer: y = 1
Step-by-step explanation:
12,500 / 100 = 125 125 x 4.5 = 562.5 562.5 x 4 = 2250
2250 + 12,500 = 14,750 He paid back a total of $14,750. Hope this helps :)
let the length of each shorter side be x
length of longer side= x+14
2(x+14) + 2x = 48
2x + 28 + 2x = 48
4x + 28 = 48
4x = 48-28
4x = 20
x = 5
shorter side = 5cm
Step by Step:
Step 1.) Subract 10 from both sides.
Step 2.) Divide each side by one
answer: x=15
