Answer:
A and C
Step-by-step explanation:
The segment was only rotated, not changed. It would be the same length as the original.
To find the length, use the distance formula.

(5, 8) would be point 1.
(-6,8) would be point 2.
Plug them into the formula.

Simplify.



Square root this answer.

Negative distances aren't possible, so your answer is 11.
Hope this helped!

Answer:
For part a)
130 = 10/2[2a+(10-1)d]
Simplify, u get
2a + 9d = 26.................(1)
Also U5 = a + (5-1)d = 3a
Simplify, u get
a= 2d...................(2)
Substituting for a in equation 1,
2(2d)+9d= 26
Solving for d, we get
d = 2
In part b) substituting for d in equation 2 to get the first term
a = 2(2) = 4
Part c) the no. of terms required can be obtained by solving
28 = 4+(n-1)2
n = 13
I think is the one on the top left but not really sure, and wish you luck with that lesson.
