Step-by-step explanation:

[Note: The solutions are done by using the distributive property of addition and subtraction i.e a(c+b) = ac+ab]

(a) 8x(y-1)

= 8xy-8x

(b) -9x(3y-2z)

= -27xy+18xz

(c) 3x(2a+7y)

= 6xa+21xy

(d) 3y(x-11y)

= 3yx-33y²

(e) -3a(2a+3b)

= -6a²-9ab

(f) -4c(2c-5d)

= -8c²+20cd

(g) -6h(7k-3h)

= -42hk+18h²

(h) -8m(-12m-7n)

= 96m²+56mn

(i) 2p(3p+q+7r)

= 6p²+2pq+14pr

(j) -7s(s-4t-3u)

= -7s²+28st+21su
