The volume is 70. 5 x 4 is 20 divided by 2 is 10 times 7 = 70.
Answer:
Mean of boiling times = 26.9 seconds
Step-by-step explanation:
Times ella recorded are given as;
24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.
Now, we want to find the mean of these boiling times.
Formula for mean is;
Mean = sum of terms/number of terms
In this question,
number of terms = 4
Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6
Thus,
Mean = 107.6/4
Mean = 26.9 seconds
8t2u2, 2t2u2, and 4t2u2 are like terms, so we subtract them, and we are left with 0, so the answer is what remains; 7w3.

We want to see in which other situations we can see that two things look different, but the meaning is still the same like when working with algebra.
<h3>Synonyms.</h3>
Trivially, when you wrote sentences you can choose the words that you use, and for a complete sentence, you can easily change a word by a synonym of it, in such a way that the meaning of the sentence does not change.
A similar thing happens when we apply algebra to an equation to "rewrite" it in another form.
The question particularly talks about rewriting polynomials, but this can actually be applied to all mathematical expressions.
For example, we can just rewrite the number 2 as:
√4
Notice that are 2 really different ways of writing the same number.
