Serggg [28]

Answer:

(-∞ , -6] ∪ [6 , +∞)

Step-by-step explanation:

<u>Let D be the domain of f </u>.

D = {x ∈ IR ; where  x² - 36 ≥ 0}

x² - 36 ≥ 0

⇔ x² ≥ 36  

⇔ x² ≥ 6²

⇔ √(x²) ≥ √(6²)

⇔ |x| ≥ 6

⇔ x ∈ (-∞ , -6] ∪ [6 , +∞)

5.6 gallons of paint are needed to cover 1,960 square feet. 

two gallons are needed for 700, so divide 700 by 2 to get square feet per gallon. 

then divide 1,960 by 350 to get the gallons of paint needed

5.6 gallons
