Are we alone in the Universe,we living beings on Earth? Answer: i think no cause there are some creatures that is unidentified and also we do not now what creature is that or where is that from like aliens. god didnt create planets without a reason.
Find the indicated product of (2r-5) (2r-5) show your solution :) using FOIL method (2r-5) (2r-5) First term (2r)(2r) = 4r^2 Outer term (2r)(-5) = -10r Inner term (-5)(2r) = -10r Last term (-5)(-5) = 25 4r^2 - 10r - 10r + 25 4r^2 - 20r + 25 or by using the algebraic property thingie such that (a - b)(a - b) = a^2 - 2ab + b^2 (2r-5) (2r-5) a = 2r b = 5 so 4r^2 - 2(2r)(5) + 25 4r^2 -20r + 25
