Which expression is equivalent to 5(y + 3) + 9?

A) 5y + 15 + 9
B) 5y + 8 + 9
C) 5y + 3 + 9
D) 5y + 15 + 45

Use the distributive property to move the 5 into the brackets...

that is
5xy + 5x3 + 9
...
5y +

To simplify the expression 5(y + 3) + 9, we need to distribute the 5 to both terms inside the parentheses.

Step 1: Distribute the 5 to y and 3:
5 * y = 5y
5 * 3 = 15

After distributing, the expression becomes:
5y + 15 + 9

Step 2: Combine like terms:
15 + 9 = 24

The final simplified expression is:
5y + 24

Therefore, the equivalent expression is B) 5y + 24.

To find the expression that is equivalent to 5(y + 3) + 9, we need to simplify the expression by applying the distributive property.

Step 1: Distribute the 5

5(y + 3) + 9 = 5 * y + 5 * 3 + 9

Step 2: Simplify

Simplifying further, we have:

= 5y + 15 + 9

Step 3: Combine like terms

= 5y + 24

So, the expression equivalent to 5(y + 3) + 9 is 5y + 24.

Looking at the answer options, we can see that the correct answer is not provided. There should be an option for 5y + 24.

the answer is A :)
