So I'm going to assume that this question is asking for <u>non extraneous solutions</u>, or solutions that are found in the equation <em>and</em> are valid solutions when plugged back into the equation. So firstly, subtract 2 on both sides of the equation:
Next, square both sides:
Next, subtract x and add 2 to both sides of the equation:
Now we are going to be factoring by grouping to find the solution(s). Firstly, what two terms have a product of 6x^2 and a sum of -5x? That would be -3x and -2x. Replace -5x with -2x - 3x:
Next, factor x^2 - 2x and -3x + 6 separately. Make sure that they have the same quantity on the inside of the parentheses:
Now you can rewrite the equation as
Now, apply the Zero Product Property and solve for x as such:
Now, it may appear that the answer is C, however we need to plug the numbers back into the original equation to see if they are true as such:
Since both solutions hold true when x = 2 and x = 3, <u>your answer is C. x = 2 or x = 3.</u>
The <span>ratio of adam's height to sam's height is 4:3. Therefore, Sam's height is 3/4 of adam's height. This is done by applying rules on ratios. We do as follows:
4 / 3 = adam's height / sam's height
sam's height = (3/4) adam's height
Hope this answers the question. Have a nice day.</span>
Answer:
71.3 ft
Step-by-step explanation:
Oliver has a piece of string that is 214 ft long. He needs to cut this string into 3 pieces that are all the same length.
To find the length that each piece should be, we divide the length of the string by 3:
214 / 3 = 71.3 ft
Each piece should be 71.3 feet long.
Answer:
$1095.6.
Step-by-step explanation:
A 12% discount (12% off) means that the customer will save 12% of the full price. The full price here is equal to $1,245. The customer will thus save
