Is (x^3 -1)/x odd or even?
I believe the answer is even if you divide them out.
7+14+21+28+...+105=1*7+2*7+3*7+4*7+...+15*7
15
∑7*n=7*1+7*2+7*3+7*4+...+15*7=7+14+21+28+...+105
n=1
Answer:
31 yards of ribbon
Step-by-step explanation:
Of after purchasing the ribbon in bulk she has $21.28 left from her initial $25 it would mean that she spent $3.72 in total.
