I have solved this on a different website, and here is my solving in a picture. I hope I helped!!! :D
Answer:
sorry i dont know this this is very hatd question necause i cant have studied
If you want to solve this problem using formulas, there are two important formulas:
t1 = first term = -5
tn = nth term = last term = -5
n = numbr of terms
Sn = sum of the n terms
tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)
65 = -5 + 5n - 5
65 = -10 + 5n
75 = 5n
n = 15
Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2
Sn = 450
So ur answer rounds up to 450
Letter c

Answer:
06 + 10
Step-by-step explanation:
a2 + b2
(3x2) + (5 x 2)
6 + 10
therefore option A is the correct answer
The slope is the change in Y over the change inX: Using the two points given: (3,9) and (1,3)
The slope is (9-3) / (3-1)
Slope = 6 / 2
Slope = 3
The answer is A.
