Answer:

Step-by-step explanation:

a) 2x + y + 4 for x = 6 and y = 4

2x + y + 4

= 2×6 + 4 + 4

= 12 + 4 + 4

= 20

c) - 3abc-3 for a = 1, b = 2 and c = 3

- 3abc-3

= - 3×1×2×3 - 3

= - 18 - 3

= - 21

b) 8x^2 + 5xy - y for x = 3 and y = 2

8x^2 + 5xy - y

= 8× 3^2 + 5×3×2 - 2

= 72 + 30 - 2

= 100

d) 9x^2 + 3x + 2 + 4 for x = 5

9x^2 + 3x + 2 + 4

= 9×5^2 +3×5 + 6

= 225 + 15 +6

= 246
