Find each sum or difference. (x2-3x + 1) - (x3 + 7 – 12x) Oa. 2x3 - 15x + 8 Ob.-12x + 8 c. 9x - 6 d.-9x – 6​

(2-3x+1)-(3x+7-12x)

(2+1-3x)-(3x-12x+7)

(3-3x)-(-9x+7)

3-3x--9x+7

3-3x+9x+7

3+7+9x-3x

10+6x or 6x+10

hope it helps

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70
