I am clueless when it comes to math plz help if u can..

its B. 4x(5-4y)

Step-by-step explanation:

20x-16xy

4x(5-4y)    distribute the 4x

4x(5) and 4x(-4y)

4*5=20 and dont forget the x, so its 20x

4*-4=-16 and dont forget the previous y and the x so its -16xy

put it together and its 20x-16xy

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
