x=3 and x= -2
Step-by-step explanation:
we could simplify it to x*2 + x -6 = 0
then 2 numbers whose sum is 1 and product is -6
the numbers are 3 and -2
Answer:
10 , 8
Step-by-step explanation:
because those numbers match up with the x
If I understand your sequence, then this is the "closed form" of the sequence:
a_n = 63 - 4 n
Sum = (59, 55, 51, 47, 43, 39, 35, 31, 27, 23, 19, 15, 11, 7, 3) = 465
Would it be 4:5 because 12 and 15 can be divided by 3 so 12 divided by 3 is 4 and 15 divided by 3 is 5 so your answer would be 4:5. I hope I helped
