Answer: 210
Step-by-step explanation:
We know that the number of combinations of n things taken r at a time is given by :-

So, number of ways to select 3 plants out of 7 = 
Also number of ways to arrange them in 3 positions = 3! = 6
Now , total number of arrangements with 1 plant in each spot = (number of ways to select 3 plants out of 7) x (number of ways to arrange them in 3 positions)
= 35 x 6
=210
Hence, required number of ways = 210
Both angles have a measure of 125°.
<h3>
How to find the measure of the angles?</h3>
Assuming the two horizontal lines are parallel, we know that the measure of the two indicated angles must be the same one.
Then:
-1 + 14x = 12x + 17
Now we need to solve this for x:
14x - 12x = 17 + 1
2x = 18
x =18/2 = 9
Now that we know the value of x we can replace it in any of the expressions for the angles:
-1 + 14*9 = 125°
Both angles have a measure of 125°.

Answer:
y = 2/3 x
Step-by-step explanation:
slope = m = 4/6 = 2/3
y-intercept = b = 0
Equation: y = mx + b
y = 2/3 x
Answer:
The two shorter sides have to be equal and the two longer sides have to be equal.
Step-by-step explanation:
Answer:
It is the same as a normal equation with an equal sign. If you were to divide by a negative, the inequality sign would flip to point to the other side of the inequality.
