D'(1,3)
Answer:
35
Step-by-step explanation:
j(j + 3) = 1330
Trial and error method:
j and j + 3 are pretty close to each other. Start by taking the square root of 1330.
sqrt(1330) = 36.5. One number is less than 36.5 and the other number if 3 more than that.
Since the product of j and j + 3 is 1330 which ends in 0, it is a multiply of 10 and 5.
Try 35 and 38. 35 * 38 = 1330
Answer: 35
Equation method:
j(j + 3) = 1330
j^2 + 3j - 1330 = 0
(j + 38)(j - 35) = 0
j = -38 or j = 35
Answer: 35
Step-by-step explanation:
If triangles ADB and EDC are similar, then corresponding sides are proportional, from which we conclude:
BC/CD = AE/ED
BC / 21 = 6 / 18
Multiply by 21 on both sides,
BC = 6*21 / 18 = 21 / 3 = 7 units.
(note: Length BC is the same as length CB).
