Answer:

15z² + 39z + 24

Step-by-step explanation:

(3z+3)(5z+8)

(3z×5z) + (3z×8) + (3×5z) + (3×8)

15z² + 24z + 15z + 24

15z² + 39z + 24

Using FOIL you multiply each term in the first set of parentheses by each term in the other set, then combine all like terms:

(3z+3)(5z+8)

3z x 5z = 15z^2

3z x 8 = 24z

3 x 5z = 15z

3 x 8 = 24

So you now have:

15z^2 + 24z + 15z + 24

Simplify to:

15^2 + 39z + 24
