The perimeter of a trapezoid is 39a – 7. Three sides have the following lengths: 9a, 5a + 1, and 17a – 6. What is the length of
Airida [17]
We know the perimeter is the total sum of all sides of the shape, we can use this to form an equation: the perimeter=1st side + 2nd side + 3rd side + 4th side 39a-7=9a+(5a+1)+(17a-6)+4th side.
Collect like terms to get 39a-7=31a-5+4th side
If we move everything but the 4th side over to the left we can solve 
C. 8a-2=4th side is the correct answer

What is the value of i^97 - i
Vesna [10]

Answer:

0

Step-by-step explanation:

i^1 = i

i^2 = - 1

i^3 = i^2 * i = - 1

i^4 = i^2 * i^2 = -1 * -1 = 1

Now the circle just repeats itself. So what you do is find out the remainder of i^97 which you divide by 4. What you get is 24 with a remainder of 1.

So i^97 = i

i - i = 0

The answer is 0
