a^n + a^n+1
rewrite a^n+1 as a^1 a^n
now you have a^n + a^1a^n
Factor out the common term to get the final answer:
a^n (1+a)
<u><em>Answer: A. 30. x=30/ 30=x *The answer should be the positive sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
subtract by 15 both sides of an equation.
x+15-15=45-15
simplify.
45-15=30
30+15=45
45-30=15
x=30 and 30=x
Hope this helps!
Thanks!
Have a great day!
X= -12 and that’s you answer
