12. Work backwards to write a quadratic equation that will have solutions of x = -1/2 and x = 4. (Your equation must only have integer coefficients, meaning no fractions or decimals.)

13. Write a quadratic equation that will have a solution of only x = 0. Note: this means there will be a double solution of x = 0.

14. Write a quadratic equation that cannot be factored.

15. The product of two consecutive positive integers is 72. Find the integers.

16. The product of two consecutive negative integers is 10506. Write a quadratic equation that you could solve to find the integers.

17. Write a quadratic equation to find two consecutive odd natural numbers whose product is 63. Then find the numbers.

the correct is answer is a 9-sided polygon!

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.

i think it would be 42cm
