expand 3(x+7)
3(x+7) = 3x + 21
thank you :)
You're welcome.
To expand the expression 3(x + 7), you can use the distributive property. The distributive property states that for any real numbers a, b, and c:
a(b + c) = ab + ac
Now let's expand the given expression step by step:
1. Start by distributing the 3 to both terms inside the parentheses:
3(x + 7) = 3 * x + 3 * 7
2. Simplify the multiplication:
3(x + 7) = 3x + 21
Therefore, 3(x + 7) expands to 3x + 21.
