First,
(x•1)+(x/1) = x+x
Then,
x+x=2x
A.)
3×4=12; 12×4= 48; 48×2= 96; 96+1= 97
B.)
3×4=12; 12+4=16; 16×2= 32; 32+3=35
C.)
3×4=12; 12+4=16; 16×2= 32; 32+1=33
The answer is B
If their are 32 kids and their are 8 slices in a pizza then just divide 32 by 8 and you get 4. 4 pizzas for each student to get 1 slice each.
Remember the quadratic formula determinant?
If b^2 -4ac < 0, a complex root exists.
So for this problem, m^2 - 4q is the determinant, and if less than 0, is complex.
So a=-m/2 and b=(1/2)SQRT(m^2 - 4q)
