Answer:
If Lawrence has 24 beads and divided them into 4 groups you want to see how many he put into each group first
To do this we are going to take 24/4=6
Each group has 6 in it
If he gave one group to his sister, than he gave 6 beads to his sister
Now we want to take 6 away from 24 to find out how many he has left
24-6=18
He now has 18 beads
Hope this helps ;)
1) you can expand the brackets, simplify, set the equation = 0 and then do a double bracket factorisation.
2)
therefore Josh's solution is wrong asx = 7 and x= -1

Answer:
The answer should be A. .
Step-by-step explanation:
Start with the second inequality, which is more straightforward than the first. Add to both sides of this equation to separate from the numbers:
. The direction of the inequality sign shall stay the same.
.
On the other hand, simplifying the first inequality takes a bit more work. Start by dividing both sides by . However, keep in mind that dividing or multiplying both sides of an inequality with a negative number will invert the direction of the inequality sign. For example, the left-hand side of an inequality might have been greater than the right-hand side. When both sides are multiplied with a number less than zero, the new left-hand side would become smaller than the new right-hand side.
Because is a negative number, dividing both sides of the first inequality inequality by will turn the "greater-than" sign into a "less-than" sign.
The inequality used to be:
.
After dividing both sides by the negative number , it becomes:
.
.
.
The question connected the two original inequalities with "or". Therefore, the conditions will be satisfied as long as either of at least one of the two inequalities is true. Note, that is true whenever is true. Therefore, any real number that is smaller than will meet the requirements- not just those that are smaller than .
The corresponding interval will be .
