In the given triangle the lines are parallel.We can apply Triangle proportionality theorem.
The theorem states: If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
We can form a proportion using this theorem :
To solve x we cross multiply:
5x=18
Dividing both sides by 5 we get
x=3.6
Second option.
Use the Side Splitter Theorem (also known as the Basic Proportionality Theorem)
5/3 = 6/x
5x = 3 * 6
5x = 18
x = 3.6
Answer: B. 3.6

Its consecutive: x + 1
Product:
x(x+1)=121
x² + x - 121 = 0
Δ = 1² - 4.1.(-121)
Δ = 1+484
Δ = 485
As square root of 485 is not integer, do not exist two consecutive numbers with product of 121

Then in 1 year the California palm tree grew = (85/5) inches
= 17 inches
Again
A queen palm tree in 8 years grew = 96 inches
In 1 year the queen palm tree grew = (96/8) inches
= 12 inches.
So the California palm tree is growing at a faster rate than the queen palm tree. This is the easiest way of solving this kind of problems. Hope that i have explained the problem enough for you to understand and attempt such problems in the future without anyone's help.

Answer:
The number is 5
Step-by-step explanation:
if 3 is added to a number and the sum is tripled, the result is 19 more than the number
(n+3) *3 = n+19
Distribute the 3
3n +9 = n+19
Subtract n from each side
3n-n +9 = n-n+19
2n +9 = 19
Subtract 9 from each side
2n+9-9 = 19-9
2n =10
Divide by 2
2n/2 =10/2
n=5
The number is 5
Answer:
(x + 3)·3 = x + 19 --> x = 5
