Question

Help me with questions 3 & 4

Answer 1

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 =
`(2)/(3)`

A is negative while the others are all positive.

Thus A is the smallest value expression
