ABCD is a parallelogram ⇒ BE = DE
So: 7x - 12 = 3x + 4
⇔ 7x - 3x = 4 + 12
⇔ 4x = 16
⇔ x = 16/4 = 4
⇒ BE = 7(4) - 12 = 28 - 12 = 16
⇒ DE = 3(4) + 4 = 12 + 4 = 16
⇒ BD = BE + DE = 16 + 16 = 32
Answer: BD = 32
Ok done. Thank to me :>

And finally, adding the two terms, we find
Answer:
36 cm
Step-by-step explanation:
arc length = r × θ
32π = r × 8/9π
r = 36

For the table, y = 25x.
When x = 12, y = 25*12 = 300
For the graph, y = 30x
When x = 12, y = 30*12 = 360
When x = 12, the value of y on the graph is 60 more than its value in the table.
