The rule for multiplying similar bases with exponents is:
(a^b)*(a^c)=a^(b+c)
In this case you have:
(x^9)(x^2)
x^(9+2)
x^11
Well sure, go w that and see what you get
Answer:
Step-by-step explanation:
x+y=12
x-y=18
Now eliminate the y by adding the two equations together to get
2x=30
x=15
then solve for y.
15+y=12
15-y=18
y= -3
Answer:
it is commutative property of add
Step-by-step explanation:
commutative propert:
a+b=b+a
same as
5x-8=-8+5x
