Answer:
<u>Options 3, 4 and 5</u>
Step-by-step explanation:
Given:
F(x) = x³ + 3x² - 25x - 75
Factor the given function:
F(x) = x³ + 3x² - 25x - 75
⇒ take x² a common from (x³ + 3x²) and (-25) a common from (- 25x - 75)
F(x) = x²(x+3) - 25 (x+3)
⇒ take (x+3) as a common
F(x) = (x+3) (x² - 25)
(x² - 25) = (x-5) (x+5)
∴ F(x) = (x+3) (x-5) (x+5)
<u>The answer are options 3, 4 and 5</u>
Answer:
Jane used 2/5 of a scoop more of brown sugar than she did with white sugar.
Step-by-step explanation:
If you want to find how much more something is from something else, you subtract. So, subtract 9/10-1/2. If you want to subtract, they should both have the same denominator. So, 9/10-1/2 is the same as 9/10-5/10. 9/10-5/10 is equal to 4/10 which is simplified to 2/5.
