To rewrite this expression we can use the sum of cubes identity:
. Notice that we can express 8 as a cube:
, so we can rewrite our first term as
. Since our second term does not have a exact cubic root, we must rewrite as
. Now we have
and
, so lets use the sum of cube identity to rewrite our expression:
We can conclude that we can use the sum of cubes identity to rewrite the expression <span>8x^3+243 as </span>
Her first mistake was in step 2.
When taking an absolute value of some number let’s say x, equals to the distance it is from 0
So |x| = x as well as |-x|=x because they have the same distance from 0. 2 and -2 are both 2 unit from 0.
So in the problem, her second step was to add |-2| and |6| to get her first distance. She was supposed to remove the | | by taking the absolute value of |-2|, which is makes the equation 6+2 because |-2|=2. She just removed the signs without applying the function. Her answer should’ve been 8 for that distance not 4. Therefore her area should have been 32, not 16.

2/5 of 500= 200 times 0.40=£80
the rest 500-200=300
3 oranges for 50p. 100 times 0.5 =£ 50 over £130
Sam made a loss (140-130=£10)
Answer:
Yes.
Step-by-step explanation:
18 gal = 288 cups.
(1 gal = 16 cups)
If 240 students purchase 1 cup each, there will be 48 cups left over.
So,yes, there will be enough punch for everyone.
