Answer:

20-2(n-1)

Step-by-step explanation:

The general term (or the nth term) of this sequence is [20-2(n-1)].

Verification:

1st term = 20-2(1-1) = 20-2(0) = 20-0 = 20

2nd term = 20-2(2-1) = 20-2(1) = 20-2 = 18

3rd term = 20-2(3-1) = 20-2(2) = 20-4 = 16

4th term = 20-2(4-1) = 20-2(3) = 20-6 = 14

Answer:

6x^2√x

Step-by-step explanation:

6 times 6 is 36

So you can take 6 out and leave x^5

However x^5 also have a power to square by:

x^4 which can turn into x^2

So we can take x^2 out

So the answer is 6x^2√x

Hope this helps!

Answer:

x = 37

Step-by-step explanation:

Vertically opposite angles are equal

Therefore, 2x + 6 = 80

Subtract 6 from both sides: 2x = 74

Divide both sides by 2: x = 37

Which is longer 2 meters or 200 cent a meters or 2.05 meters

Yuri [45]

Solving this requires use of conversions

we already know that
2.05 m > 2 m

all that's left is the question
200 cm vs. 2.05 meters

I we know our equivalencies, we know that
100 cm = 1 m

if this is so then
200 cm = 2 m

we already know that
2.05 m > 2 m

so it must also be that
2.05 m > 200 cm

$2.05 \: meters$
