Find the next four terms in the arithmetic sequence. -15, -7, 1, a. 7, 13, 19, 21 b. 10, 19, 28, 37 c. 9, 17, 25, 33 d. 7, 15, 25, 37 select the best answer from the choices provided a) a b) b c) c d) d

Correct choice is C

Step-by-step explanation:

The first term of arithmetic cequence is -15, the second term is -7, the third term is 1 and i.e.

The difference between two consecutive terms of the arithmetic sequence is the difference of the arithmetic sequence. Thus, the difference of the arithmetic sequence is

Hence,

Next four terms are 9, 17, 25, 33.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
