Mark as brainlieat.

Step-by-step explanation:

i)

$5m \times (3 - m) \\ = 5m \times 3 - 5m \times m \\ = 15m - 5 {m}^{2}$

ii)

$(6 {m}^{2} - 13m) \times 5m \\ = 6 {m}^{2} \times 5m - 13m \times 5m \\ = 30 {m}^{3} - 65 {m}^{2}$

iii)

$4y \times (3 {y}^{2} + 5y - 7) \\ = 4y \times 3 {y}^{2} + 4y \times 5y - 4y \times 7 \\ = 12 {y}^{3} + 20 {y}^{2} - 28y$

iv)

$3pq \times (p - q) \\ = 3pq \times p - 3pq \times q \\ = 3 {p}^{2} q - 3p {q}^{2}$

v)

$2pq \times (p + q) \\ = 2pq \times p + 2pq \times q \\ = 2 {p}^{2} q + 2p {q}^{2}$
