What about this one ??
V125BC [204]
The first expression is equivalent to B

The second expression is equivalent to A

The third expression is equivalent to C

You are basically adding like terms. For example for the first expression, it is 7x^2 + 2x^2, which equals 9x^2. Remember since you're adding, do not add the exponents.

Please help with this inequality.
iren [92.7K]
44\geq -3x + 2 > 14.
-2                                -2      -2

42\geq -3x > 12
-------------------------------------
-3                          -3       -3 (dividing with inequalities by a negative flips the inequality symbol)

-14\leq x < -4
