Answer:
The perimeter is 
cm.
Step-by-step explanation:
Perimeter is found by adding all sides of the triangle together. So, this is what we need to find: 
- Only <u>like radicals</u> can be added or subtracted from one another. They'll have the same root number (which seems to be true for this question) as well as the radicand, which is the number/expression under the radical.
Look at the number under the radical: 7, 63, and 28. These numbers all share a factor of 7: 7/7 = 1, 63/7 = 9, 28/7 = 4.
Notice how 9 and 4 are perfect squares, so we can simplify the radicals using this common factor of 7.
remains the same; 
; and
. Now they are like radicals and can be added!
<h3>
Answer: D) The data repeats every 4 minutes</h3>
Explanation:
The period of a function measures how long a cycle takes. Think of tides on a beach. There's a regular pattern that can be predicted whether its high tide or low tide. Time is often the critical component with the period. Since choice D mentions time and the key term "repeat", this is why it's the answer.
The other values, while useful elsewhere, aren't going to tell us anything about the period. The initial value being 5 doesn't tell us when y = 5 shows up again, and if the function is repeating itself at this point or not. So info about choice A is not sufficient to determine the period. The same goes for choices B and C as well.
3 TIMES 2 = 6 + 2 = 8 + 299999999999999999999999 = 300000000000000000000007.

Answer: Addition property of equality
Step-by-step explanation: You added the x to the other side, which is clearly using addition. Hope this help!
