2. Use the distributive property to write an expression that is equivalent to 5( -2x - 3). You may consider using the boxes to help organize your work.

Example of how to write an equivalent expression using only addition.
Ex: 153 - 7 + 92 - 87
Subtracting a number can be rewritten as plus a negative. So 
a - b is the same as a + (-b)
