Answer:
8:4 completely simplied would be 2:1
Step-by-step explanation: Think of 8:4 as a fraction (8/4) so that would mean it would simplify to 2/1 or the ratio of 2:1.
Answer:
Step-by-step explanation:
- These are our given values.
- Use substitution so we only have to solve for 1 unknown, .
- Distribute the negative sign into what was substituted in for . Remember that every value in the parentheses is affected by the negative, and that <em>a negative times a negative equals a positive</em>.
- ().
- After distributing, we only have addition and subtraction remaining, so we can get rid of the parentheses.
- Now, let's add like terms.
Our final answer is:
If you wanted to solve for to see if you could get an actual number as an answer:
- Our previously final answer is a standard-form quadratic equation. Standard-form will always be formatted like so:
- where , , and are 3 different, constant values.
- At this point, we will need to use the quadratic formula to find . The equation is shown below:
- <em>NOTE 1: the values in this formula correspond to the standard form equation shown above. </em>
- <em>NOTE 2: please treat the </em><em> symbols as a ± symbol because this site does not let me type ± when doing an equation.</em>
- <em>NOTE 3: Factoring does not work in this case, so I'm resorting to the quadratic equation, but if you can, avoid using this equation as it is tedious and time consuming.</em>
- Now, let's solve for .
- No solution because you cannot square root a negative and get a real number as your answer.
- I could go into the use of or , but even this would not result in clean math and would just be a pain to solve.
