Answer: If x =7, then x + 2 = 9 and x + 4 = 11. These are your three consecutive odd integers.
Step-by-step explanation:
Step-by-step explanation:
you cannot just put the actual numbers in and calculate ?
and you can't provide the correct problem statement, as it seems.
I assume you mean
an = 3n² - 1
a sequence starts with a1, so, n>=1
a1 = 3×1² - 1 = 3-1 = 2
a2 = 3×2² -1 = 3×4 - 1 = 12 - 1 = 11
a3 = 3×3² - 1 = 3×9 - 1 = 27 - 1 = 26
a4 = 3×4² - 1 = 3×16 - 1 = 48 - 1 = 47
a5 = 3×5² - 1 = 3×25 - 1 = 75 - 1 = 74
there, that is all there is to it. you really needed help with that ?
Answer:
x=12
Step-by-step explanation:
use midpoint theorem that said that the small line segment (3x+11) is half of the segment ( 9x -14)
2(3x +11) = 9x -14
6x +22 = 9x -14; distribute
6x -9x = -22-14; subtract 9x and 22 from both sides
-3x = -36; divide both sides by -3
x= 12
Answer:
0
Step-by-step explanation:
Answer:
15 feet of fencing costs $27
Step-by-step explanation:
We know 15/20 = 3/4 so...
36 x 3/4 = 27
Another way:
36 divided by 20 = 1.8
1.8 x 15 = 27
