Answer:
((23)-(7))/5
=14/5
=2.8
Step-by-step explanation:
3. -4x - 6
-3(x + 2) - x → ( distribute bracket by - 3)
= - 3x - 6 -x → (collect like terms)
=( - 3x - x) - 6 = - 4x - 6
4. A has the smallest value
A =( 2 - 3 ) = -1
B = 2 × 3 = 6
C = 2 + 3 = 5
D = 
A is negative while the others are all positive.
Thus A is the smallest value expression
When x=1 and -2 so it is C
Answer: 18
Step-by-step explanation: well 9 x 12 = 108 then divide it by 6 and yyou get 18 wich is 6 x 3
