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

Answer:

Step-by-step explanation:
First, distribute all terms

Get all terms with R onto the same side

Factor out the R

Divide by (T-S) to isolate R

Y is greater than or equal to 5. It says no less than, making the equal to possible.
The answer will be x = 8.

Answer:
The equation of the line is:

Step-by-step explanation:
Given the points
Finding the slope between the points




Using the point-slope form of the line equation

where m is the slope
substituting the values m = -1 and the point (-3, 8)



Add 8 to both sides


Therefore, the equation of the line is:
