A= first number
B= second number
C= third number
A + B + C
Then divide by 5
8:7
32:28
48:42
I think that's right, hope this helps.
Option A:
The length of BE is 4.
Solution:
Given data:
AE = 6, EC = 12 and DE = 18
To find the length of BE:
<em>If two chords intersect in a circle, then the product of lengths of one segment is equal to the product of lengths of other segment.</em>
⇒ AE × EC = DE × BE
⇒ 6 × 12 = 18 × BE
⇒ 72 = 18 × BE
Divide by 18 on both sides of the equation.
⇒ 4 = BE
Switch the sides.
⇒ BE = 4
The length of BE is 4.
Option A is the correct answer.
Answer:
y = -4w + x - z
Step-by-step explanation:
Multiple both sides by 4.
X=7 because 7+6=13 and 3•13=39
