Answer:
2r+6
24s-6
2(4t+1)
Explanation:
The act of multiplying a number to the numbers inside a parenthesis is called the Distributive Property.
When a number is presented with a small expression in the parenthesis, we distribute that number to every expression term in the parenthesis.
Ex. r(x+y)
rx+ry
Imagine drawing a r to both x, and y. Arrows can help you understand.
For the first problem, we distribute 2 to r and 3. We multiply it and get 2r+6
For the second, we distribute 6 to 4s to get 24s, and 6 to '-1' to get -1.
For the third, you need to work backwards. Since the answer's distributing term is a 2, divide the given equation by two.
