4k+6 is greater or equal to -14
4k is greater or equal to -20
k is greater or equal to -5 <-- answer
He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47
Answer:
They can make 4 teams.
Step-by-step explanation:
You can see that 24 cannot be divided by 5, but you can subtract 4 from 24 to get 20, which is a multiple of 5. 20 divided by 5 is 4, so they can make 4 teams.

Because LP and NP are the same measure, that means that MP is a bisector. It bisects side LN and it also bisects angle LMN. Where MP meets LN creates right angles. What we have then thus far is that angle LMP is congruent to angle NMP and that angle LPM is congruent to angle NPM and of course MP is congruent to itself by the reflexive property. Therefore, triangle LPM is congruent to triangle NMP and side LM is congruent to side NM by CPCTC. Side LM measures 11.
