Answer: Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
Step-by-step explanation:
The roots would be x=-5 and x=-4 but with that website you just do -5 and -4
X is a element of all real numbers but there is a vertical asymptote at x=o. Mathematically: XeR, x≠0
It would be D because when you divide fractions, you multiply by the reciprocal of the fractions so 2/5 * 10/9. Then you simplify and get 4/9. Hope this helps!!!!!!!
