1.89 * 10^12
1.89e +12
e is shorthand for *10^(
The given expression is
81x²y³ + z
When x=3, y=4, z=19, then
81x²y³ + z
= 81*(3²)*(4³) + 19
= 81*9*64 + 19
= 46,675
Answer: D 46,675
Answer:63x
Step-by-step explanation:
Divided and subtracted
Then calculated the product
1 1/3 = 4/3 (because (3 * 1 + 1) / 3)
We need both parts of sum to have common denominator.
Second part have denominator = 6.
When we multiply nominator and denominator of first part by 2 we get 8/6 (what is legit operation on fractions)
Now easily add:
8/6 + (- 5/6) = 8/6 - 5/6 = 3/6 (here we can divide both nominator and denominator by 3 to get "nicer" result) = 1/2
The answer is B
Reason Being is because you would combine (4x) and (-10x) which would give you -6x.
After combining those you would combine (7) and (15) which would give you 22.
Therefore, your answer is (22-6x)
