Use the distributive property to expand the expression: 4(y + 5x)

Given Expression:
4(y + 5x)
Since, the given expression is in the form of a(b+ c) we can apply Distributive Law which yields ab+ ac as a result.
Similarly, By applying the Distributive Law to 4(y + 5x):
4(y + 5x)
= 
= 4y + 20x.
Hence, the expression 4(y + 5x) becomes 4y + 20x after it's expansion.
