Answer:
B. 3
Step-by-step explanation:
A common difference in an arithmetic sequence is the value the terms in the sequence vary from one to another.You can find one term to another by adding or subtracting the common difference.
In this case, the terms are 2,5,8,11,.....
From the first term to the second term, the difference is, 5-2=3
From the second term to the third term, the difference is, 8-5=3
From the third term to the fourth term the difference is=11-8=3
Hence the common difference in this arithmetic sequence is 3
1. LCM of 15x^7 and 45x^7
2. Marla can shovel the driveway in 60min and Bill can do it in 45min how long would it take them to do the job together?
3. Divide and simplify:
x^2-4/x divided by x+2/x+8
4. add and simplify:
5/49z^3 + 1/35z^2
5. simplify by removing factors of 1
y^2-5y+6/y^2+3y-18
6. divide and simplify:
h+1/h-3 divided by 6h+6/h-1(simplify answer)
7. add and simplify:
5/v-9 + 5/v+9
Answer:
17 I think it's 17 considering the 45 went to 35
Answer: 7
Step-by-step explanation:
They are alternate interior angle
2x + 5 = 3x -2
2x = 3x -7
-x = -7
x = 7
