Just think 200% = 2x, so 2x of 18 = 36. Now for the 20%. Thats one fifth, so just do 18/5 and you have your answer when you add those together
The answer is C. 7 x ( 2 x 2 )
Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x



BD ≈ 5.36
Y=x-5
6=x-5
6+5=x-5+5
11=x
x=11
