Find the Error A student simplified the expression 5x−3(x+4) to 2x+12 . Choose the correct answer and explanation. Multiple choice question. cross out A) The student did not multiply −3 by x. 5x−3(x+4)=2x+4 cross out B) The student did not multiply 5x by 4. 5x−3(x+4)=17x cross out C) The student multiplied 4 by 3 instead of −3 . 5x−3(x+4)=2x−12 cross out D) The student did not add 4 to −3 . 5x−3(x+4)=6x+1

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
