6x^2 is the correct answer to the problem.
You're dividing where you need to multiply. The intersecting chord theorem says
5(12)=7.5 x
x = 5(12)/7.5 = 8
Choice F
You need to find two factors of 20 that are consecutive: 4,5.
Answer: 5inx4in
Answer:
AD = 84
Step-by-step explanation:
Since B is the midpoint of AC then AB = BC = 2x - 5
Since C is the midpoint of AD then AC = CD, thus
AB + BC = CD, that is
2x - 5 + 2x - 5 = x + 29
4x - 10 = x + 29 ( subtract x from both sides )
3x - 10 = 29 ( add 10 to both sides )
3x = 39 ( divide both sides by 3 )
x = 13
Hence
AD = AB + BC + CD
= 2x - 5 + 2x - 5 + x + 29 = 5x + 19, thus
AD = (5 × 13) + 19 = 65 + 19 = 84

a is the correct not sure though
