1. 9+6x divided by 3
9+6(5) divided by 3
9+30 divided by 3=10+9=19
2. (7-x)+2x2
(7-3)+(2)(3)(2)
4+12=16
3. 6ab+2
(6)((2)(3)+2. 36+2=38

9+6(5)/3=9+30/3=39/3= 13
(7-x)+2x2=(7-3)+2x2=4+2x2=4+2*3 2=4+6*2=4+12=16
6*2+6*3+2=12+18+2=30+2=32

9+6(5)/3=9+30/3=39/3= 13
(7-x)+2x2=(7-3)+2x2=4+2x2=4+2*3 2=4+6*2=4+12=16
6*2+6*3+2=12+18+2=30+2=32

2. should be 4 if it is written correctly (7-x) + 2*2 or if it is (7-x) + 2x^2, it should be 22.
