scientific notation

4x10^6,

9.85x10^8

Step-by-step:

Write out the whole number. Count from the period in the number (4,000,000.00 in this case) and then count how many numbers there are until the first number (in this case, 4). There are 6 places before 4, so it will be 4x10^6. If you are going from a smaller number to a bigger number, such as .00001, count from left to right. It would be 1x10^-5

the answer

b. they are parallel and will never intersect.

(23*2)-12=x     x=34
