Answer:
I don't understand the question?
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
X = -4, nothing else, its just vertical
Hey download Socratic and just take a pic of the question
To change a decimal into a percent,
move the decimal point 2 places that way ==> .
Examples:
