Answer:
21
Step-by-step explanation:
BDE and BAC are similar figures
BD/BA = BE/BC
18/(18+36) = a/(a+42)
18/54 = a/(a+42)
1/3 = a/(a+42)
a+42 = 3a
42 = 2a
a = 42/2
a = 21
5 and 8/12= 5 and 2/3= 17/3
2 and 6/36= 2 and 1/6=13/6
17/3-13/6 Need common denominator
34/6-13/6=21/6=3.5 or 3 and 1/2
Answer:
The length of the third side, L, is greater than 4 and less than 14.
4 < L < 14
Step-by-step explanation:
The length of any side of a triangle is between the sum and difference of the lengths of the other two sides.
sum of lengths of the 2 sides: 9 + 5 = 14
difference of length of 2 sides: 9 - 5 = 4
The length of the third side is greater than 4 and less than 14.
4 < L < 14
Answer:
ans x=4
Step-by-step explanation:
- 5x + 7 = -13
- 5x = -13 -7
- 5x= -20
- x = -20/5
- x = -4
- so the answer is x= -4
3/18=1/6
