Answer 5

FOIL stands for first,outside,inside,last
(8z + 3)(5z + 4)

First -- multiply first terms in each set....8z * 5z = 40z^2
Outside -- multiply outside terms in each set ... 8z * 4 = 32x
Inside -- multiply inside terms in each set .. 3 * 5z = 15z
last -- multiply last terms in each set ... 3 * 4 = 12

Now we have :
40z^2 + 32z + 15z + 12 -- combine like terms
40z^2 + 47z + 12 ===> your answer
