Basically what you have to do is multiply the two numbers that are mentioned and that will be your answer.
This is because the item will have the same amount or length and you just need to find what it will be with multiple ones.
Next time you could highlight keywords that help you understand if you are supposed to multiply, divide, subtract, or add.
The correct answer is A. <span>The independent variable is the temperature of the water, and the dependent variable is the amount of sugar dissolved. The independent variable is the one that isn't affected by any of the other variables. The dependent variable is the one being studied, measured, and affected in the experiment. Obviously, Eman wants to measure the amount of sugar that dissolves in water.</span>
Answer:
<h2>A, B, D, E</h2>
Step-by-step explanation:
2(2x + 1) = (2)(2x) + (2)(1) = 4x + 2 → A
<em>used distributive property</em>
2(2x + 1) = 2(1 + 2x) → B
<em>used commutative property</em>
2(2x + 1) = (2x + 1) + (2x + 1) = 2x + 1 + 2x + 1 → D
<em>used 2a = a + a</em>
2(2x + 1) = 4x + 2 = x + x + x + x + 1 + 1 → E
<em>used 4x = x + x + x + x and 2 = 1 + 1</em>
