need help rewriting it

distributive property of multiplication states: a(b+c) is equal to (ab + ac).

So in your case we need two numbers inside the parentheses that add up to 26. Pick any combination.

let's try 14 and 12.

so we have:

3(26) = 3(14 + 12) = (3* 14 + 3 * 12)

3(26) = 78

(3* 14 + 3 * 12) = (42 + 36) = 78

therefore, a(b + c) = (ab + ac)
