(a-y)+2y3,if a= 2 and y= -3
(2--3)2 + 2(-3)3
(5)2 + (-6)3
25 + -216
-191 either im wrong somewhere or my book doesnt have that answer my choices are -29,43,79,-53
I am assuming that by 2(-3)3 you mean
2(-3)3
you did not follow the order of operation which says exponents before multiplying
that part should then be
2(-27)
so your last line is
25 + (-54)
= -29
