Which expression is equivalent to 9(4+r)?
To find the expression that is equivalent to 9(4+r), we can distribute the 9 to both the 4 and the r.
9(4+r) = 9 * 4 + 9 * r
Multiplying, we get:
= 36 + 9r
Therefore, the expression that is equivalent to 9(4+r) is 36 + 9r.
To find an equivalent expression to 9(4+r), you can use the distributive property. The distributive property states that when you have a number (in this case 9) multiplied by the sum of two terms (in this case 4 and r), you can distribute the multiplication to each term individually.
To apply the distributive property, you multiply 9 by each term within the parentheses separately.
First, multiply 9 by 4:
9 * 4 = 36
Next, multiply 9 by r:
9 * r = 9r
Putting it all together, the equivalent expression to 9(4+r) is 36 + 9r.
I assume you mean to expand the product. If so, that would be
9*4 + 9*r = 36+9r
