Answer:
4x -3
Step-by-step explanation:
The distributive property applies.
3x +4(x -6) -3(x -7)
= 3x +4x +4(-6) -3x -3(-7) . . . . use the distributive property
= 3x +4x -24 -3x +21 . . . . . . . . simplify
= x(3 +4 -3) +(-24 +21) . . . . . . . group like terms, use the distributive property again
= 4x -3 . . . . simplify

Answer: option D. 2x^2 + (3/2)x - 5
Explanation:
1) polynomials given:
f(x) = x/2 - 2 and g(x) = 2x^2 + x - 3
2) question: find (f + g) (x)
That means that f(x) + g(x), so you have to add up the two polynomials given.
3) x/2 - 2 + 2x^2 + x - 3
4) Combine like terms:
a) terms with x^2: you only have 2x^2, so it is not combined with other term.
b) terms with x: x/2 + x
that is a sum of fractions: x/2 + x = [x + 2x] / 2 = 3x / 2 = (3/2)x
c) constant terms: - 2 + (-3) = - 2 - 3 = - 5
5) Result: 2x^2 + (3/2)x - 5
That is the option d.
