發問:
Which of the following is a prime number? A.35 B.49 C.53 D.87 Simplify the following algebraic expression.(要過程) A. 3r + 4s - 2r+7s b. a+2b+3c+4a-6b-2c C. 2xy+3x-2y+4x-6y+5xy
最佳解答:
Which of the following is a prime number? A.35 =7*5 B.49 =7*7 C.53 D.87 =29*3 Answer : C Simplify the following algebraic expression.(要過程) A. 3r + 4s - 2r+7s =3r-2r+4s+7s =r+11s b. a+2b+3c+4a-6b-2c =a+4a+2b-6b+3c-2c =5a-4b+c C. 2xy+3x-2y+4x-6y+5xy =2xy+5xy+3x+4x-2y-6y =7xy+7x-8y
吾系啊嘛 -.- 但系個d我未教個啵;; 但系我又吾會去補習,,,,|||||求做作業會俾人話違規嫁! 小心d牙! 你都係自己做啦! 或者你問補習老師仲好啦! 問補習老師就唔會俾人話違規! 我都係咁問,不過我琴日岩岩問就俾人話我求做作業,違規! 仲扣左我好多分! (我係要唱衰yahoo,yahoo你中意洛,你咪del晒我回d野囉!不過我會係第2度再唱你咁姐~)
