If u need to show work do 250 x .18
*if u don’t mind brainliest answer pls
Answer:
Step-by-step explanation:
First your going to plug in what p and q are into the equation so 3(2)^5+10(-3)^2 over 7(2)+1.
Your going to first do (2)^5 and (-3)^2 so it’s going to be 3(32)+10(9) over (multiply the 7(2) first) 14+1.
3(32)+10(9) over 14+1 now multiply 3(32) and 10(9) you should get (96)+(90) over 15.
add 96+90 to get 186 over 15.
then divide how many times 15 can go into 186 you should get 12 6/15 and divide 6/15 by 3 to get your final answer 12 2/5.
I hope this helps!
x³ + 2x² - x - 2 < 0
x³ - x + 2x² - 2 < 0
x(x² - 1) - 2(x² - 1) < 0
(x - 2)(x² - 1) < 0
(x - 2)(x - 1)(x + 1) < 0
by chacking we get the solution
x ∈ (-∞,-1) ∪ (-1,1)
