Natasha2012 [34]

Answer:

Mixed fraction: 1 and 3/4

Improper fraction: 7/4

Step-by-step explanation:

Mixed: You have 1 whole circle and only three out of four pieces of an other circle

Improper: Add the colored pieces of the two circles together but because the circles are divided into fourths, the number four is the denominator or bottom number. Therefore, you get seven over four(7/4) as the improper fraction

1. What is the sum or difference?
Vanyuwa [196]

<u>Solving question 1 : What is the sum or difference? </u>

4x^{10} - 9x^{10} \\\\ (4-9)x^{10} \\\\ -5x^{10}

Hence, option A is correct i.e. -5x^{10}.

<u>Solving question 2 : What is the sum or difference? </u>

6x^{5} - 9x^{5} \\\\ (6-9)x^{5} \\\\ -3x^{5}

Hence, option D is correct i.e. -3x^{5}.

<u>Solving question 3 : Write the Polynomial in standard form. </u>

2 - 11x² - 8x + 6x²

We can combine like terms, and rewriting it in decreasing power of x's.

⇒ - 11x² + 6x² - 8x + 2

⇒ (-11 + 6)x² - 8x + 2

⇒ -5x² - 8x + 2

Hence, option A is correct i.e. -5x² - 8x + 2; quadratic trinomial.

<u>Solving question 4 :</u>

White-sided jackrabbits: 5.5x² - 9.2x + 6.9

Black-tailed jackrabbits: 5.5x² + 9.9x + 1.3

Total population = White-sided jackrabbits + Black-tailed jackrabbits

Total population = (5.5x² - 9.2x + 6.9 ) + (5.5x² + 9.9x + 1.3)

Total population = (5.5 + 5.5)x² + (9.9 - 9.2)x + (6.9 + 1.3 )

Total population = 11x² + 0.7x + 8.2

Hence, option A is correct i.e. 11x² + 0.7x + 8.2
