12a + 6 + 3a = 15a + 2
15a = 15a - 4
0 = - 4
The answer is C. You shouldnt cheat and actually learn though it will help you in the future.
Answer:
1.25 would be the leading coefficient
Step-by-step explanation:
Leading coefficients in scientific notation have to be more than 1, and less than 10. Therefore, 12.5 or 0.125 would not be correct answers as they do not fit the criteria. Only 1.25 would work as the leading coefficient.
Answer:
362881
Step-by-step explanation:
The right sequence should be
2,3,7,25,121,721,5041,40321, 362881
Here, the formula used is a(n)=n!+1 where n=1 to infininity
n(1) =2=1!+1=2
n(2)= 3=2!+1=3
n(3)=7=3!+1=7
n(4)=25=4!+1=25
n(5)=121=5!+1=121
n(6)=721=6!+1=721
n(7)=5041=7!+1=5041
n(8)=40321=8!+1=40321
n(9)=362881=9!+1=362881
