Answer:
You can determine the root of the equation by multiple methods. However, that answer is correct. The root is -2.
Step-by-step explanation:
A root is where the graph crosses the x-axis. One trick I use to see if it is a root is by taking the numerator and plugging in the number for x. For example, 
, and take the -2 and plug it in for x. The numerator would cancel out because -2 + 2 = 0. That is the way you can determine if it is a root or not.
I hope this helps, if you need any clarification let me know :)
Answer:
B. 8x - 3
C. 8x + 12
Step-by-step explanation:
64 is a perfect square, meaning it has two factors that are identical (8), and 36 is also a perfect square, but in this case, you don't see two 6's in the answer choices.
12 and -3 give you a product of -36, so your answer choices would be:
(8x - 3) (8x + 12)
If you're unsure, you can multiply them together to check if they come out to the unfactorized expression.
Answer:
I think the second one is the answer ; 2√b
Answer:
One. first what you want to do you want to convert 20% into a decimal and a way to do that you need to move a decimal two times to the left. when finding the percent of something you will always move the decimal two times to left
now that you have your 20% into a decimal you will multiply 145 by .20
after you have multiply 245 by .20 you should have gotten 29.00
