The two triangles are similar. The two marked sides 16 and 2x-6 are connected in such a way that the longer side (16) is exactly twice as long as the shorter side (2x-6)
In other words
longer side = 2*(shorter side)
16 = 2*(2x-6)
Let's solve for x
16 = 2*(2x-6)
16 = 2*2x+2(-6)
16 = 4x - 12
4x - 12 = 16
4x - 12+12 = 16+12
4x = 28
4x/4 = 28/4
x = 7 which is the answer
If there are 20 red seeds in each bag, then there are 20*2=40 green seeds in each bag.
There are 40*5=200 green seeds in 5 bags.
Answer:
16=x becuase 16/4 also =4 and 4+2=6 may i have brainliest plzz
Step-by-step explanation:

Answer:
a.
Period = π
Amplitude = 4
b.
Maximum at: x = 0, π and 2π
Minimum at: x = π/2 and 3π/2
Zeros at: x = π/4, 3π/4, 5π/4 and 7π/4
Step-by-step explanation:
Part a:
Amplitude represents the half of the distance between the maximum point and the minimum point of the function. So the easy way to find the amplitude is: Find the difference between maximum and minimum value of the function and divide the difference by 2.
So, amplitude will be:
Therefore, the amplitude of the function is 4.
Period is the time in which the function completes its one cycle. From the graph we can see that cosine started at 0 and completed its cycle at π. After π the same value starts to repeat. So the period of the given cosine function is π.
Part b:
From the graph we can see that the maximum values occur at the following points: x = 0, π and 2π
The scale on x-axis between 0 and π is divided into 4 squares, so each square represents π/4
Therefore, the minimum value occurs at x = π/2 and 3π/2
Zeros occur where the graph crosses the x-axis. So the zeros occur at the following points: π/4, 3π/4, 5π/4 and 7π/4
