What is the quotient of 3.12 x 109 and 2.6 x 10 expressed in scientific notation?​

Step-by-step explanation:

b. contain the points P and Q

Step-by-step explanation:

a. be parallel to line PQ and pass through point N

cannot pass through point N, since PQ did not pass througn N

b. contain the points P and Q

Yes, the centre of dilation passes through PQ, so any dilation P'Q' will always contain the original points PQ.

c. be perpendicular to line PQ and pass through point L

P'Q' cannot be perpendicular to PQ because dilations preserve parallelism.

d. shift two units to the right

A dilation about the centre (assumed origin) will not shift with respect to the same centre if the factor of dilation is to be respected.
