The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.
Which of the following is not an integer?

\({1 \over 2}\) |
An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.
A tiger in a zoo has consumed 36 pounds of food in 6 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 72 pounds?

If the tiger has consumed 36 pounds of food in 6 days that's \( \frac{36}{6} \) = 6 pounds of food per day. The tiger needs to consume 72 - 36 = 36 more pounds of food to reach 72 pounds total. At 6 pounds of food per day that's \( \frac{36}{6} \) = 6 more days.
What is \( 6 \)\( \sqrt{48} \) + \( 2 \)\( \sqrt{3} \)
| 12\( \sqrt{48} \) | |
| 12\( \sqrt{16} \) | |
| 8\( \sqrt{144} \) | |
| 26\( \sqrt{3} \) |
To add these radicals together their radicands must be the same:
6\( \sqrt{48} \) + 2\( \sqrt{3} \)
6\( \sqrt{16 \times 3} \) + 2\( \sqrt{3} \)
6\( \sqrt{4^2 \times 3} \) + 2\( \sqrt{3} \)
(6)(4)\( \sqrt{3} \) + 2\( \sqrt{3} \)
24\( \sqrt{3} \) + 2\( \sqrt{3} \)
Now that the radicands are identical, you can add them together:
24\( \sqrt{3} \) + 2\( \sqrt{3} \)a(b + c) = ab + ac defines which of the following?

commutative property for division |
The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.
