PLEASE HELP AND SHOW ALL STEPS
Alja [10]

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

N a triangle, the measure of the first angle is 24 degrees more than the measure of the second angle. The measure of the third a
almond37 [142]

x + 24 = first angle


x = second angle


4x = third angle


x + 24 + x + 4x = 180°


6x + 24 = 180°


6x = 180° - 24


6x = 156°


x = 156° ÷ 6


x = 26°....the second angle.


x + 24 = 26 + 24 = 50°.... the first angle.


4(26) = 104°


The largest angle is the third angle, which measures 104°.
