Answer:
5x+4
Step-by-step explanation:
Combine like terms: <u>12x</u>+4<u>-7x</u>
Notice that the 7 is being subtracted, as it's negative
So 36% of x is 18
percent is parts out of 100
36%=36/100=0.36
'of' can be translated as muitiply
0.36 times x=18
divide both sdies by .36
x=50
the number is 50
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.
