60 total fourth graders and 43 are girls. To find the number of boys, subtract.

60 - 43 = 17 boys

If 5 girls were absent, subtract.

43 - 5 = 38 girls present

If 4 boys were absent, subtract.

17 - 4 = 13 boys present

Therefore, there were 13 boys present.

Best of Luck!

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
