4. Find the product of the following. i) -5a2bc, 6ab, 8abc2
ii) 3x2y and (5y - xy)
iii) x2y2z2 and (xy - yz + zx)
iv) (p + 6) and (q – 7)
v) (2x + 7) and (x2 – 5x + 6)
vii) (x + y + 5) and (2x – 2y - 3)

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
