Combining the like terms, the simplified polynomials are given as follows:
a) 4x² - 14x + 17
b) -5x² - 20x + 8
<h3>How are polynomials simplified?</h3>
Polynomials are simplified combining the like terms, that is, adding these numbers with the same variable.
Item a:
4(x - 2)(x + 1) - 5(2x - 5)
Applying the distributive property:
4(x² - x - 2) - 10x + 25
4x² - 4x - 8 - 10x + 25
Combining the like terms:
4x² - 4x - 10x - 8 + 25
4x² - 14x + 17
Item b:
-5(x + 2)² + 28
-5(x² + 4x + 4) + 28
-5x² - 20x - 20 + 28
-5x² - 20x + 8

It will equal 1 Kg because 1ml = 1 gram
The answer is A, it’s the only one that makes sense
Answer:
X= 1
Step-by-step explanation:
2, + the 2 her brother gives her is too high, its 4.
which means we go lower.
0 can't be right, because 0 + 2 = 2, not 3.
lets try 1.
1 + 2 = 3.
So that means X = 3.
