What is the binomial expansion of (x + 2y)?? O 2x + 14x®y + 42x5y2 + 70x4y2 + 70x/A + 42x²y + 14xy + 2y?
O x + 14x®y + 42x® y2 + 70x*y2 + 70xⓇJA + 42x2y + 14xy + y
O x + 7x®y + 21x$y2 + 35x^y2 + 35x+y+ 21x2y + 7 xy + y
O x + 14x®y + 84x® y2 + 280x*y* + 560x®y4 +672x2y + 448xy + 128y?

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

i can

step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
