Answer: x² - 4
<u>Four less than</u> the <u>square of a number</u>
↓ ↓
(Take away 4) x²
Four less than the square of a number = x² - 4
Răspunsul corect va fi numărul 4. Supãrat dacã meu vorbind nu este cel mai bun, vorbesc limba engleza. Dacă ai nevoie de numere consecutive, sunt 99, 102 şi 103.
Let Mia's score be
![x](https://tex.z-dn.net/?f=x)
. Then, Erick scored 10 more than Mia, so his score is
![x+10](https://tex.z-dn.net/?f=x%2B10)
. Isabelle scored 16 less than twice Mia's score, so her score is
![2x-16](https://tex.z-dn.net/?f=2x-16)
. We can see that
![x + x + 10 + 2x - 16](https://tex.z-dn.net/?f=x%20%2B%20x%20%2B%2010%20%2B%202x%20-%2016)
is the sum of these variables, so
the expression represents the total of their scores in this scenario. Moreover, we recall that the variable in the expression,
![x](https://tex.z-dn.net/?f=x)
,
represents Mia's score.To simplify this expression, we add up the variables and the numbers separately, giving us
![x+x+10+2x-16 = (x+x+2x) + (10-16) = 4x-6](https://tex.z-dn.net/?f=x%2Bx%2B10%2B2x-16%20%3D%20%28x%2Bx%2B2x%29%20%2B%20%2810-16%29%20%3D%204x-6)
. Therefore, in simplified form, the expression is equal to
4x - 6. The constant term
in an expression is the term not multiplied by a variable, so in this case, it is
-6.
