Answer:
x + 2
Step-by-step explanation:
Replace the x with y.
Making is x = y -2
Solve for x=y-2
and you get x+2
Answer:
Yes
Step-by-step explanation:
Given that a teacher prepares 26 tiles with 5 vowels numbered 1 and 21 consonants numbered 2.
The probability for drawing vowel =
Prob for consonant =
If number of trials is atleast 30 we can expect reliable results.
Here the results are recorded for 120 times at random.
Since number of trials is large, we can expect a reliable and accurate results representing the actual probability.
This is because more the number of trials, the less would be the margin of error i.edeviationfrom the expected probability would be minimum
Id there are 21 girls according to my calculations there would be a heap amount of boys which is 23
Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.
Thus your answer should be C, x^3
A. -14x+21
because -7 times 2x is -14x and -7 times -3 is 21
