Answer:
1. Solution ~ This is usually the answer to you variable which is x=3
2. Distributive ~ In this example you distribute or multiply the 2 to x and -1 to get 2x-2
3. Multiply ~ In this example the distributive property is involved, just like I said before, you have to multiply each number in the parenthesis to get the correct answer or in this case multiply a by 5 and 3 by 5 to get you 5a+15
4. Expanded form ~ Expanding is the equation you have after distribute for example, 4b+8 is the expanded form but the original was 4(b+2)
5. Properties of equalities ~ This means multiply the same quantity by both sides of an equation
6. Area model ~ A great visual tool because it can be used to make sense of virtually any fraction and distributive problems. It allows kids to see the numbers with shading.
