D. 5 and 6
Someone please help!!

  C.  3 and 4

Step-by-step explanation:

The squares nearest to 12 are ...

  3² = 9

  (√12)² = 12

  4² = 16

Then something whose square is 12 will be between 3 and 4.

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
