To expand and simplify 5(x + 4) 3(x + 2), we can use the distributive property of multiplication over addition which states that a(b + c) = ab + ac.
So, we have:
5(x + 4) 3(x + 2) = (5x + 20)(3x + 6)
Now, we can use the distributive property again to expand this expression:
(5x + 20)(3x + 6) = 5x * 3x + 5x * 6 + 20 * 3x + 20 * 6
= 15x^2 + 90x + 60
Therefore, the answer is 15x^2 + 90x + 60.
I hope this helps!
