1. d
3g = 3 (-2)
=-6
2.a
3k+4=3 (3)+4
=9+4
=13
3.b
2h^2=2 (4)^2
=2 (4×4)
=2 (16)
=32
4.e
5m-k=5 (1)-3
=5-3
=2
5.c
6h-g^2=6 (4)-(-2)^2
=24-(-2×-2)
=24-4
=20
Answer:
1. D. -6 because 3g = 3(-2) = 6
2. A. 13 because 3k+4= 3(3) = 9+4= 13
3. B. 32 because 2h²= 2(4)²=2(16) =32
4. E.2 because 5m-k = 5(1) -3 = 2
5. C. 20 because 6h-g²=6(4) -(-2)²=24-4=20
