Answer:
I'm sure the answer to this question is A
Answer: common difference is 14
Step-by-step explanation:
a,a+d,a+4d
7,7+d,7+4d
(7+d)/7=(7+4d)/(7+d)
(7+d)(7+d)=7(7+4d)
49+14d+d^2=49+28d
d^2-14d=0
d(d-14)=0
d=0 or d-14=0
d=14
b = sin of angle B times length of c
b = 24*sin(62) = 21.1907
= 21.2
answer is A
42*3/6 is equal to 42*1/2, or 21.
I think it will be 2:4. 2X9=18 so u × 4×9=36 so its 18 to 36
