Step-by-step explanation:

f(x) = 4x - 1

g(x) = 3x - 2

1) f(x) + g(x) = (4x - 1) + (3x - 2)

= 4x - 1 + 3x - 2

= 4x + 3x -1 - 2 = 7x - 3

2) f(x) * g(x) = (4x - 1) * (3x - 2)

= 12x^2 - 8x - 3x + 2

= 12x^2 -11x + 2

3) f(g(x)) = 4(3x - 2) - 1

= 12x - 8 - 1

= 12x - 9

4) f(x) - g(x) = (4x - 1) - (3x - 2)

= 4x - 1 - 3x + 2

= 4x - 3x - 1 +2

= x + 1

Step-by-step explanation:

4. To use SSS, you need three pairs of congruent sides. You're given two pairs of congruent sides, so the additional information needed is WY ≅ KM.

5. To use ASA, you need a pair of congruent sides between two pairs of congruent angles. You're given one pair of congruent angles, and since the triangles share a common side, we know BC ≅ BC. So the additional information needed is ∠WBC ≅ ∠ACB.

6. To use SAS, you need a pair of congruent angles between two pairs of congruent sides. You're given two pairs of congruent sides, so the additional information needed is ∠I ≅ ∠F.
