How many dots are in the 4th step

24

Step-by-step explanation:

if we observe carefully we can see that the difference in the number of dots from the first picture to the second picture is 5

and the difference in the number of dots from the second picture to the third picture is 7

so there might be a chance that the difference between the 3rd figure and 4th figure may be 9

so my answer is the number of dots in the 3rd picture + 9

15+9= 24

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
