Answer:
L = a √( 4 + 2√2)
Step-by-step explanation:
L = a √( 4 + 2√2) is the equation which can be used to calculate the length of each side of the octagon. In the equation i.e. L = a √( 4 + 2√2), in which ''a'' is the length of each side of the octagon. So by putting of ''a'' we get the length of each side of the octagon. The octagon is regular means all of its sides and angles are congruent or similar to each other. Each angle in the octagon has a measure of 135 degrees.
Answer:
Below.
Step-by-step explanation:
The common ratio = 1.6 / 0.2 = 8, 12.8 / 1.6 = 8.
The nth term = an = 0.2(8)^(n-1).
Answer:

Step-by-step explanation:

The way you want to do this is to make all the numbers into a fraction. You do that by multiplying the whole number by the denominator, or the bottom of the fraction, then adding that to the numerator, or the top of the fraction.
So,
becomes
, and
becomes
.
Then, you find the least common denominator. The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. In our case, that would be 4, since 2 can multiply into 4.
So,
is multiplied by 2, and becomes
.
stays the same.
And finally, you subtract. When subtracting or adding fractions, you leave the denominator alone, and only work with the top number.
So,
, which equals
.
Now, you could technically stop there. However, most teachers ask that you put it back into whole number form. To do that, divide the numerator by the denominator, and whatever remains goes back into the fraction.
So, 
That's your answer! Hope this helps.
4x^7

8y^6
this is the simplified answer. you flip negative powers.
The slope is -3. You would use the equation:
M=y2-y1/x2-x1 to find slope.
