Answer:

Step-by-step explanation:

Two secants drawn to a circle from a common external point, then

The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

5(5 + x) = 4(4 + 10) = 4 × 14 = 56

25 + 5x = 56 ( subtract 25 from both sides )

5x = 31 ( divide both sides by 5 )

x = 6.2 → C

AB = 9 cm
BC = 6cm

CD = 7 cm
AE = 6 cm

3BC = AB
3ED = AE

  AB = AE
  BC ED
  ⁹/₃ = ⁶/ₓ
3 · 6 = 9 · x
18 = 9x
9 9
2 = x

ED = 2 cm

2 Simplifica -21x-28+21x−21x−28+21x a -28−28.

-28=-28

−28=−28
