Answer:
x=12
Step-by-step explanation:
see Image below:)
You could put,
19
+ 6
———
25
Then write,
19+6=25
If you're just supposed to expand, then start by grouping together terms of the same base.
which is true since multiplication is commutative/associative. By definition of exponentiation, we have
and the same goes for the remaining bases. So the fully simplified form of the expression above would be
Answer:
2/11
Step-by-step explanation:
To turn a repeating decimal to a fraction:
1) Multiply by the number of digits repeating to the power of 10. In this case, there are two digits repeating.
x=0.1818...
100x=18.1818...
2) subtract x
99x=18
3) divide by 99
x=18/99
4) simplify
x=2/11
|-1/5| < |-1/3| < |-7|
Your answer:
B. y = -1/5 x^2; y = -1/3 x^2; y = -7x^2
