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

(35 Points)<br> Evaluate ƒ(x) when x = 6.
pychu [463]

The value of the function is 6

Step-by-step explanation:

The function that we have in this problem is

f(x)=\left \{ {{3x^2+1}, -4

This means that:

when x is between -4 (excluded) and 6 (excluded), the value of the function is 3x^1+2

when x is between 6 (included) and 9 (excluded), the value of the function is 6

In this problem, we are asked to evaluate f(x) when x = 6. Therefore, we are in the second case: therefore, the value of the function is 6,

f(x)=6

Is 44.11 greater than 44.5
Aleks04 [339]
No because I'll teach you a trick. Put a zero after the 5.   so now you have 44.11 and 44.50 . So 44.5 is bigger!
