Use distributive property to write an equivalent
7 (u+4+h)
multiply each term, as usual, for example,
3(1+4+9) = 3*1 + 3*4 + 3*9
now use your values
To use the distributive property to expand the expression, distribute the number outside the parentheses (7 in this case) to each term inside the parentheses.
7(u+4+h) = 7u + 7(4) + 7(h)
Simplifying each term:
7u is the product of 7 and u.
7(4) is the product of 7 and 4.
7(h) is the product of 7 and h.
So, the expanded form of the expression 7(u+4+h) is 7u + 28 + 7h.
