Answer:
c) x^6 y^11 z^6
Step-by-step explanation:
When multiplying exponents with the same variables, you add them.
so x^4(x^2) would be 4+2 and therefore x^6.
keep in mind this doesn't apply for different variables
(xy^2)(x^2y) will not be added!!
Answer:
5
Step-by-step explanation:
If two is subtracted from a number: let's give the number a name and call it X . And this difference is tripled: so we get 3(X−2) . The result is 4 more than the number, so
3(X−2)=4+X .
We want to know X so we need to get it to one side of the equation. That's done by repeatedly doing the same operation on both sides of the equation. First get rid of the parentheses:
3X−6=4+X.
Now subtract X and add 6 :
2X=10
Divide by 2:
X=5
